Selection Behavior Improvements:
- Limit selection to parent services only (docker, nginx, postgresql, etc.)
- Skip sub-services in navigation (no longer select nginx sub-sites)
- Up/Down arrows now move between actionable services only
Visual Enhancement:
- Preserve original status colors in selection highlighting
- Selected services show blue background with status foreground colors
- Green text for active services, red for failed, even when selected
- Maintains visual health status information during selection
Selection Logic:
- Add parent service index mapping for accurate selection tracking
- Only count parent services in total service count
- Calculate proper parent service index from display line position
- Ensure selection highlights only apply to parent services
This creates a cleaner UX where users only select services they can
actually control (start/stop/restart) while maintaining visual health
status indicators through preserved status colors.
Visual Highlighting Fixes:
- Apply selection highlighting to individual text spans instead of entire paragraph
- Eliminates highlighting of empty space below services on single-service hosts
- Selection now only highlights actual service text content
Selection Logic Improvements:
- Add proper bounds checking in select_next() to prevent invalid selections
- Automatically clamp selection index when services are updated
- Add debug logging to track selection state and movement
Bounds Safety:
- Ensure selection index stays valid when service lists change
- Prevent out-of-bounds access during service updates
- Reset selection to last valid index when services are removed
This fixes the issues where:
1. Single service hosts showed empty space highlighting
2. Multi-service hosts had no visible selection cursor
3. Selection could become invalid when services changed
Service Selection Features:
- Add selection cursor for Services panel with visual highlighting
- Up/Down arrows move service selection instead of scrolling
- Track selected service for future action implementation
- Selection state maintained per host

- Show all repositories when scrolling instead of truncated list
Navigation now works correctly with actual UI layout and
provides proper service selection for future action implementation.
- Remove Network panel from navigation cycle
- Fix system panel scrolling to work in both directions
- Add complete scroll support to Services and Backup panels
- Update panel cycling to System → Services → Backup only

- Clean up unused Network panel code and references
Resolves issues with non-functional up/down scrolling and
mystery network panel appearing during navigation.
The new keybindings (Shift+Tab, Up, Down, BackTab) weren't working because
the main app.rs event loop was only passing specific keys to the TUI app.
Added handling for:
- KeyCode::BackTab (Shift+Tab panel switching)
- KeyCode::Up (scroll up in focused panel)
- KeyCode::Down (scroll down in focused panel)
Now all keyboard navigation features work correctly.

- Host navigation (Tab key) now works correctly with all hosts in alphabetical order
Fixes issue where only 3 of 5 hosts were accessible via Tab navigation.
- Remove predefined host order that was causing random display order
- Sort hosts alphabetically for consistent title display
- Localhost is still auto-selected at startup but doesn't affect display order
- Title will now show: cmbox ● labbox ● simonbox ● srv01 ● srv02 ● steambox
Eliminates confusing random host order in dashboard title bar.
- Add has_data() method to BackupWidget to check if backup metrics exist
- Modify dashboard layout to conditionally show backup panel only when data exists
