feat(tui): move detail panel from bottom overlay to right side

Restructure dashboard from [Monitors 70% | Logs 30%] to
[Monitors 45% | Detail 55%] master-detail layout. Detail panel
now sits beside the monitor list instead of below it, keeping
dashboard context visible during inspection.

- Detail panel renders in horizontal split (right of monitors)
- Logs sidebar removed; `l` key opens fullscreen logs directly
- recalcLayout no longer subtracts detail height from table rows
- Remove unused renderCompactLogLine/viewLogsSidebar (Phase 4 recreates)
