feat(applock): 4-digit PIN gate at app launch (#4093)

Closes #2285. Adds an opt-in 4-digit PIN that gates the library and reader on app launch. Threat model: casual physical/browser access by another person on a shared device — peace of mind, not defense against an attacker with filesystem access. The PIN is stored as a salted PBKDF2-SHA256 hash (100k iterations) in settings.json; the plaintext PIN is never persisted. Configured from Settings → Advanced Settings → "Set PIN…" (and "Change PIN…" / "Disable PIN…" once enabled). The lock screen and the set/change/disable dialog share a single 4-dot input component (PinInput) for a consistent UI; the dialog auto-advances focus from Current → New → Confirm. Lock-on-resume, biometric unlock, and account-based reset are out of scope for this MVP — disable for now is "clear app data". Bundles the previously-missed sync-passphrase i18n strings (PR #4090) across all 33 locales so no `__STRING_NOT_TRANSLATED__` placeholders remain in the tree. New - src/libs/crypto/applock.ts (PBKDF2 hash/verify; reuses derivePbkdf2Key) - src/store/appLockStore.ts (gate + dialog state) - src/components/PinInput.tsx (shared 4-dot input) - src/components/AppLockScreen.tsx (full-screen lock gate) - src/components/settings/AppLockDialog.tsx (set/change/disable) - src/__tests__/libs/crypto/applock.test.ts Modified - src/types/settings.ts (pinCodeEnabled / pinCodeHash / pinCodeSalt) - src/services/constants.ts (default off) - src/components/Providers.tsx (mount gate + dialog above app shell) - src/app/library/components/SettingsMenu.tsx (Advanced submenu entries) - src/styles/globals.css (animate-pin-shake keyframe) - public/locales/*/translation.json (21 PIN keys + 17 leftover passphrase keys × 33 locales) Verified - pnpm test (4018 pass) - pnpm lint (clean) - Manual web smoke: Set/Reload-locks/Wrong-PIN/Unlock/Change/Disable Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
