feat: add interactive catalog dashboard TUI (Quick Win #13)

- Implement `dbbackup catalog dashboard` interactive TUI
- Browse backup catalog in sortable, filterable table view
- View detailed backup information with Enter key
- Real-time statistics (total backups, size, databases)
- Multi-level sorting and filtering capabilities

Interactive Features:
- Sortable columns: date, size, database, type
- Ascending/descending sort toggle
- Database filter with cycle navigation
- Search/filter by database name or path
- Pagination for large catalogs (20 entries per page)
- Detail view for individual backups

Navigation:
- ↑/↓ or k/j: Navigate entries
- ←/→ or h/l: Previous/next page
- Enter: View backup details
- s: Cycle sort mode
- r: Reverse sort order
- d: Cycle through database filters
- /: Enter filter mode
- c: Clear all filters
- R: Reload catalog from disk
- q/ESC: Quit (or return from details)

Display Information:
- List view: Date, database, type, size, status in table format
- Detail view: Full backup metadata including:
  - Basic info (database, type, status, timestamp)
  - File info (path, size, compression, encryption)
  - Performance metrics (duration, throughput)
  - Custom metadata fields

Statistics Bar:
- Total backup count
- Total size across all backups
- Number of unique databases
- Current filters and sort mode

Filtering Capabilities:
- Filter by database name (cycle through all databases)
- Free-text search across database names and paths
- Multiple filters can be combined
- Clear all filters with 'c' key

Use Cases:
- Quick overview of all backups
- Find specific backups interactively
- Analyze backup patterns and sizes
- Verify backup coverage per database
- Browse large backup catalogs efficiently

This completes Quick Win #13 from TODO_SESSION.md.
Provides user-friendly catalog browsing via TUI.
