feat/bug(frontend/mobile) - Workout Preset Duplication, Exercise Duplication and Replace, and Preset Name Fix

[Gtt1229]

Description

What problem does this PR solve?
Editing a workout preset had no way to swap or clone a single exercise, and there was no way to duplicate an entire preset. Additionally, a long preset name on mobile caused the detail screen's header buttons to be hidden/squeezed.

How did you implement the solution?

• Added the ability to replace exercises while editing a workout preset
• Added the ability to clone an exercise while editing a workout preset
• Added the ability to clone an entire workout preset
• Added a fix to reformat the screen header to fix title overlfows

Linked Issue: Closes #2185 and #2186

How to Test

1. Check out this branch
2. Via web, navigate to Workouts/Workout preset and utilize the new duplicate or replace functions.
   a. Confirm operation completed
3. Via mobile, navigate to Workouts/Workout preset and utilize the new duplicate or replace functions. Duplicate is at the bottom of the page above the "Delete preset" option
   a. Confirm operation completed
   b. Verify long preset title still shows back button, share, and edit button.

📝 Walkthrough

Walkthrough

The web and mobile applications now support workout preset and exercise duplication. Exercise replacement preserves compatible configured sets and resets incompatible sets. Mobile custom headers now prevent long titles from shrinking side actions.

Changes

Workout preset duplication

Layer / File(s)	Summary
Mobile exercise state and replacement SparkyFitnessMobile/src/hooks/draftExercisesSlice.ts, SparkyFitnessMobile/src/hooks/useExerciseSetEditing.ts, SparkyFitnessMobile/src/hooks/useWorkoutForm.ts, SparkyFitnessMobile/__tests__/hooks/draftExercisesSlice.test.ts	Mobile replacement preserves sets for compatible modalities and creates default sets otherwise. Exercise duplication creates new IDs and resets completion, server, and superset metadata.
Mobile exercise duplication controls SparkyFitnessMobile/src/hooks/useWorkoutPresetForm.ts, SparkyFitnessMobile/src/screens/WorkoutPresetFormScreen.tsx, SparkyFitnessMobile/src/components/WorkoutFormExerciseList.tsx	Preset forms expose exercise duplication through the overflow menu in create and edit modes.
Mobile preset duplication flow SparkyFitnessMobile/src/screens/WorkoutPresetDetailScreen.tsx, SparkyFitnessMobile/__tests__/screens/WorkoutPresetDetailScreen.test.tsx	The detail screen creates a private copy, preserves exercise data and order, shows pending and success states, and pushes the created preset.
Web exercise and preset duplication SparkyFitnessFrontend/public/locales/en/translation.json, SparkyFitnessFrontend/src/types/workout.ts, SparkyFitnessFrontend/src/hooks/Exercises/useWorkoutPresetForm.ts, SparkyFitnessFrontend/src/pages/Exercises/*, SparkyFitnessFrontend/src/tests/components/*, SparkyFitnessFrontend/src/tests/hooks/*	Web forms support exercise replacement and duplication. The preset manager creates translated private copies with bounded names and sequential exercise ordering. Tests cover replacement, duplication, and action visibility.

Mobile header layout

Layer / File(s)	Summary
Custom header sizing SparkyFitnessMobile/src/hooks/useScreenHeader.tsx, SparkyFitnessMobile/__tests__/hooks/useScreenHeader.test.tsx	The title uses an absolute centered layer with truncation. Left and right action areas remain content-sized and non-shrinking.

There was already another PR related to this. not sure if both of these are related. I am merging this for now as the other one is bigger system wide change & still in draft

I don't believe so. The title layout issue has to do with the dynamic positioning of the menu items rather than the text itself being cutoff unexpectedly.

[CodeWithCJ]

Could you look into the Claude comments below:

Should fix

1. Mobile duplicate navigates to the route it's already on

SparkyFitnessMobile/src/screens/WorkoutPresetDetailScreen.tsx (~L242):

navigation.navigate('WorkoutPresetDetail', { preset: created });

This runs from WorkoutPresetDetail. In React Navigation 7, navigate to the currently focused route doesn't push a screen — it replaces that route's params. So the screen you're standing on silently becomes the copy, the original detail is gone from the stack, and Back drops you to the list.

We already have the precedent for the fix: MealDetailScreen.tsx:366 uses navigation.push('MealDetail', …) for the same MealDetail → MealDetail case. Please switch to navigation.push.

Note the new test can't catch this, since navigation is mocked.

2. The header fix changes layout on all ~55 screens using useScreenHeader

SparkyFitnessMobile/src/hooks/useScreenHeader.tsx (~L738-756)

Your flexbox diagnosis is correct — basis-0% siblings get a scaled shrink factor of 0, so the title eats the whole row. But dropping flex-1 from both side cells also removes the equal-width property that kept the title geometrically centered. On a screen with no left button and an Edit on the right, the title now visibly shifts left by half the right cell's width. That applies to every screen using this hook, not just the preset detail one, and only that one screen was tested.

Either check a handful of headers (a tabs root, a form screen with Cancel/Save, a detail screen) and confirm you're happy with the shift, or keep both properties by absolutely positioning the centered title over content-sized side cells.

Secondary: flexShrink: 0 on both sides means wide left+right content can no longer truncate — it'll overflow and clip off the right edge instead. Probably fine for icon buttons, but worth knowing.

3. Replace preserves sets across a modality change

SparkyFitnessFrontend/src/hooks/Exercises/useWorkoutPresetForm.ts (~L75-93), and the mobile preserveSets branch in draftExercisesSlice.ts.

modality is swapped but the sets aren't reconciled. Replacing a timed exercise with a barbell one leaves reps: null — so the user sees a blank reps column instead of the default 10 — plus a stale duration. The reverse direction keeps reps/weight that the UI hides but the server happily persists into workout_preset_exercise_sets.

Preserving is the right behavior for a same-modality swap, which is the common case. Could you gate it: preserve when the modality is unchanged, otherwise fall back to defaultSetForModality?

Minor

• sort_order is dropped on preset duplication. getWorkoutPresets/searchWorkoutPresets don't select wpe.sort_order (workoutPresetRepository.ts:131-160), so both web (exercises: preset.exercises) and mobile (sort_order: exercise.sort_order ?? undefined) send it undefined and every row is inserted with sort_order || 0. Display order survives only via the wpe.id ASC tiebreak. Cheap to make explicit: .map((ex, i) => ({ ...ex, sort_order: i })).

• Web and mobile disagree on supersets for duplicate-exercise. Mobile deliberately clears supersetGroup and inserts after the whole group. Web spreads ...exerciseToDuplicate, and although WorkoutPresetExercise doesn't declare superset_group, the server response carries it at runtime — so the web copy silently joins the original's superset. Worth aligning the two.

• Stale pending activation — useExerciseSetEditing.ts (~L60-64): when setClientId == null the ref is left untouched rather than cleared, so an earlier activation that never fired can fire on a later transitionEnd. Safer:

  pendingActivationRef.current =
    setClientId != null ? `${exerciseClientId}:${setClientId}` : null;

• setClientIds[i] can be undefined in DUPLICATE_EXERCISE if exercisesRef is stale relative to the real set count, producing two sets with clientId: undefined (key collisions, edits hitting the wrong row). Practically unreachable, but a ?? \${action.newExerciseClientId}-${i}`` fallback costs nothing.

• The new exercises param may be unnecessary. The required positional arg on useDraftExerciseActions, the exercisesRef, and the sync effect exist only to pre-generate set ids and compute hadExistingSets — both are derivable inside the reducer, which already holds that state (deterministic ids derived from newExerciseClientId keep it pure). That would delete ~15 lines and un-thread the new param from two call sites. Optional, but it'd simplify things.

• Header comment contradicts the code and its own test: "Giving every cell in this row the same flexBasis: 0 floor" — only the title cell gets flexBasis: 0; the side cells get flexShrink: 0 with basis auto.

• Duplicating twice yields two identically-named X (Copy). Also workout_presets.name is varchar(255), so repeated duplication of a long name will eventually 500 on the insert. Both low priority.

tag me once its ready. i moved to draft for now. its easier for me to know if its completed or not this way
