fix(sorting): accent-aware library sorting with COLLATE LOCALIZED

[AmrEldeeb5]

Fixes #2164

Problem

Titles starting with accented letters (e.g. "Águas De Março") sort after Z instead of under A.

Cause

All library ORDER BY clauses in MusicDao order text with COLLATE NOCASE. NOCASE only case-folds ASCII A–Z; everything else falls back to code-point order, and accented Latin letters sit above z in Unicode (Á = U+00C1 > z = U+007A).

Fix

Use COLLATE LOCALIZED for the text orderings (title / artist / album / name) across the songs, albums, artists, liked, and folder queries. LOCALIZED is registered by Android's framework SQLite — which this app already uses via the default Room open-helper, so there's no new dependency — and it orders accented characters in their expected position, locale-aware.

• No schema migration: only @Query text changes; Room's schema/identity hash is unaffected.
• Scope is ordering only. The LIKE … COLLATE NOCASE search filter in MediaStoreSongRepository (case-insensitive matching, not sorting) is intentionally left as-is.

Alternatives considered

• COLLATE UNICODE — locale-independent/deterministic across locales. Happy to switch to this if preferred.
• A precomputed diacritic-stripped sort-key column — more robust but needs a schema migration + backfill; overkill for this.

Testing

• Project compiles; Room's annotation processor validates every modified query.
• Installs and runs with no regression to existing sorting.
• Recommend a quick on-device check: a title beginning with Á/É/Ñ now sorts within its base-letter group rather than after Z.

Note: COLLATE LOCALIZED resolves only at runtime on-device/emulator (framework SQLite), so this is validated at runtime rather than in a JVM unit test.
