fix(tui): cohesion polish across all views

- Hide nonsense latency/histogram data for group monitors in detail view
- Add missing status colors to fmtStatusWord (LATE, STALE, PENDING, etc)
- Wrap Maint and Settings tabs in titled panels to match Monitors tab
- Standardize headers: breadcrumb style (History > Name, SLA > Name)
- Standardize footer key order: actions first, [q/Esc] Back last
- Add # column to Nodes table for consistency with all other tables
- Use titleStyle for section headers (CONFIGURATION, DAILY BREAKDOWN)
- Fix panel focus not switching when clicking monitor rows from logs panel
