- Add `get_totp_secret` to `EntryManager` and `EntryService` to allow retrieving the secret (derived or imported) without calculating the code.
- Update `TotpViewerWindow` in GUI to cache TOTP secrets locally. This prevents expensive PBKDF2/BIP39 derivation on every UI refresh (every second).
- Clean up unused imports and f-strings in `entry_management.py`.
Benchmarks show a ~9x speedup for 10 frames (50 entries) and >100x speedup for steady state.
