fix: make .editorconfig actually match the Makefile

[sugat009]

Summary

.editorconfig line 10 is [{*.java, Makefile}]. In EditorConfig glob syntax whitespace inside braces is significant, so the space after the comma makes the second alternative the literal " Makefile" — with a leading space. A file actually named Makefile never matches it and falls through to [*], which sets indent_style = space, indent_size = 2.

Recipe lines in a Makefile must be tab-indented, so an editor honouring .editorconfig would silently reformat them and break make. Present since #192 (Jul 2021).

Fix is one character: [{*.java,Makefile}].

Verification

Using the editorconfig CLI, before:

$ editorconfig $PWD/Makefile
indent_style=space
indent_size=2

$ editorconfig "$PWD/ Makefile"     # the alternative the glob actually creates
indent_style=tab
indent_size=4

after:

$ editorconfig $PWD/Makefile
indent_style=tab
indent_size=4

$ editorconfig $PWD/src/main/java/org/medicmobile/webapp/mobile/MedicLog.java   # control
indent_style=tab
indent_size=4

$ editorconfig $PWD/build.gradle                                               # control
indent_style=space
indent_size=2

No reformatting needed

Nothing in the tree changes as a result: all 98 recipe lines in the Makefile are already tab-indented, and the only 3 space-indented lines sit inside an ifdef ComSpec conditional block, where make imposes no indentation requirement.

Also

Drops the caveat AGENTS.md carried about this glob (added in #432), which this fix makes untrue.

Test plan

• CI green — note this is not a docs-only PR, so Build and Instrumentation will actually run
• make test still works locally

Split out of #432 at @binokaryg's suggestion, to keep that PR docs-only.
