Security Update, Smart Recovery Improvements, and Multiple Bug Fixes

🔒 Security Update: This release fixes a security vulnerability in DBackup's own code (GHSA-h929-x237-c5h2). Update as soon as possible.

encryption: Added a "Key Required" fallback dialog for decrypted downloads and offline config restore. When Smart Recovery cannot find a matching key, users can manually select a vault profile or paste a raw hex key to complete the operation.

ftp: Fixed GFS retention on FTP servers without MLSD support by falling back to dates extracted from backup filenames when server-provided modification times are unavailable.
encryption: Smart Recovery (try-all-keys) is now applied during offline config backup restore and decrypted file downloads from the Storage Explorer - both previously failed with "Encryption Profile not found" when the profile ID changed after a key reimport. (#108)
encryption: Smart Recovery key-match heuristic now correctly identifies SQLite (.db) and Redis RDB (.rdb) backup files - previously both binary formats were misidentified as "wrong key" because they are not GZIP/PGDMP/TAR/plain-SQL.
restore: Fixed "Restore as New Database" mode silently ignoring the typed target name - switching back to "Overwrite Existing" after typing cleared the name without any indication.
sqlite: Fixed restore ignoring the target filename set in the database mapping table, causing the backup to overwrite the original file instead of creating a new one.

adapters: Adapter connection-test and access-check routes now fail closed - permission checks deny access by default instead of falling through when the check is inconclusive. Thanks @endscene665 (GHSA-h929-x237-c5h2)

retention: GFS retention calculations now use the configured system timezone for day/week/month/year bucketing instead of always using UTC.

retention: Added comprehensive GFS retention unit tests with realistic multi-month backup sets.
