Summary

Selecting Galician currently formats dates in Spanish because its dateLocale points to es. For example, formatting 1 January 2024 with EEEE, d MMMM yyyy produces lunes, 1 enero 2024 instead of luns, 1 xaneiro 2024.

Use date-fns' existing gl locale and add a regression test covering actual weekday and month output. Also correct the language's display label to "Galician". Keep the existing ga-ES settings key so saved language preferences remain compatible.

This was found while inspecting the locale mappings; there is no separate bug report. The original Galician translation was requested in #1215.

Validation

• src/lib/lang.test.ts: all 7 tests passed with Vitest 5.0.3 and date-fns 4.4.0 (the lockfile versions), run under a minimal Node-only config instead of the app's DOM setup. The new test fails with the Spanish output before the fix.
• Biome check on both changed files: passed.
• npm run lint: the 6 errors it reports are in unchanged files (the not-found page and SVG assets).
• git diff --check: passed.

Not run: the full application build and database-backed tests (no local database, limited disk space).

AI assistance was used to investigate and implement this change; the checks above were run locally.
