refactor: finish indexeddb winner selection

[ryokun6]

Summary

• promote src/utils/indexedDBOperations.ts to the shared IndexedDB CRUD entrypoint
• remove the Finder-owned generic dbOperations wrapper and update file/content consumers to import the shared helper directly
• migrate useFilesStore and useDisplaySettingsStore off routine raw IndexedDB transactions
• merge the latest main changes into this branch and restore custom-wallpapers under the logical files sync domain so merged sync APIs and tests stay aligned
• reuse the shared useThemeFlags() helper in CandyBar instead of recomputing raw theme booleans in merged UI files
• continue Wave 7 by moving auth, room typing, room message delete, and user-search client calls onto src/api/* wrappers
• fix the useFilesStore default-file rehydrate noise by normalizing malformed filesystem payloads before root-directory reconciliation
• update plans/simplification_execution_waves.md to reflect Wave 7 partial progress and the resolved rehydrate cleanup noise

Testing

• bun run build
• bun test tests/test-cloud-sync-domains.test.ts tests/test-cloud-sync-utils.test.ts tests/test-cloud-sync-backup.test.ts
• bun test tests/test-auth-extra.test.ts tests/test-new-api.test.ts tests/test-rooms-extra.test.ts
• bun test tests/test-cloud-sync-utils.test.ts

Notes

• specialized backup, migration, and sync flows still open IndexedDB directly where they need cursor/bulk behavior; routine CRUD now goes through the shared helper
• the sync-focused API test runs require the standalone API server (bun run dev:api) to be running locally
• Wave 7 is still not fully complete: other internal API wrappers and migrations remain outside the auth/rooms slice
