## Summary
Adds a "Database Explorer" feature to the debugging settings. When
tapped, displays a list of GRDB database tables. Selecting a table shows
all entries (up to 1000 rows) with:
- Text search across all columns
- Server ID filter (when table has `serverId` column and multiple
servers configured)
- Tap-through to view all fields for any row
### Changes
- **DatabaseExplorerView.swift** - Lists all tables from `sqlite_master`
- **DatabaseTableDetailView.swift** - Table entry viewer with filtering,
uses `@StateObject` ViewModel pattern
- **DebugView.swift** - Added navigation link in the existing section
with Event Log and Location History
- Localization strings added for new UI elements
### Security
- Table names validated via parameterized query before use
- SQL identifier quoting applied
- Row limit (1000) prevents memory issues on large tables

`ServersPickerPillList`. Follows `DesignSystem.Spaces` convention.
