Refs #517

Unchanged #517 fix (sidebar mini month with marked event days, highlighted range and keyboard navigation; per-user ISO week numbers setting shown in month/week grids and the mini month). The rejected share-link E2E test (calendar.spec.js:1197) could not be reproduced: it passed 13 times on its own and in a complete calendar.spec.js run (251/251), and every class check in it covers code this change does not touch, so it is probably a timing flake (not proven); the #255 side-effect test passes.

Security review (claude-fable-5-1): no blocking finding. No auth, CSRF, injection or cache-leak defects in the touched code; strict boolean validation with tests that have teeth. Non-security: server/db.js:497 adds show_week_numbers only via CREATE TABLE IF NOT EXISTS, so pre-existing user_preferences tables lack the column and /api/preferences returns 500 (fail-closed availability regression, same gap as #509). Could not run the #255 import side-effect test (sandbox denied); the diff adds no require-time work.
