Fixes two regressions surfaced after the folder browser shipped in #429: 1. Note created from inside a folder went to Unfiled - Composer now takes `folderSelection` and resolves the target folder: `folder` → that id, `unfiled`/`all` → null. The new note appears in the active folder view immediately and the folder count increments via the existing notes query invalidation. 2. No in-app back from a folder view - Added a "← Back to folders / المجلدات" chip above the composer whenever a folder or Unfiled is selected (active tab only). Tapping it resets the selection to "all" and lands the user back on the folders browser. The global header back button is unchanged. - Chevron flips for RTL via `rtl:rotate-180`. - Locale keys: `notes.folders.backToFolders` (EN/AR). Verification: - tsc --noEmit clean. - Playwright suites all green: notes-folders, notes-checklist, notes-card-touch-actions, notes-delete-confirm (8 tests).
