fix(i18n): Turkish locale-aware search and sorting (#3115)

* feat(i18n): add Turkish locale-aware text helpers (search/sort)

* test(i18n): cover null/whitespace edges + document compareTr/normalize contract

* fix(i18n): route dashboard search through Turkish-safe matchesSearch

* fix(i18n): sort user-visible lists with Turkish collation (compareTr)

* fix(i18n): keep providerId tiebreaker as ASCII sort (technical id)

* docs(i18n): document intentional lang=en in global-error boundary

* chore(lint): guard against locale-unsafe toLowerCase().includes search

* fix(i18n): migrate missed provider-name search + harden lint disable placement

* fix(i18n): downgrade no-restricted-syntax to warn (incremental adoption)

The rule errored on ~19 pre-existing toLowerCase().includes() call-sites in
src/app accumulated since this PR's base. Keep it as a warning so the guard-rail
guides future code without breaking the 0-errors lint gate (project policy:
0 errors, warnings tolerated).
