Implement per-service disk usage monitoring

Browse Source 
Replaced system-wide disk usage with accurate per-service tracking by scanning
service-specific directories. Services like sshd now correctly show minimal
disk usage instead of misleading system totals.

- Rename storage widget and add drive capacity/usage columns
- Move host display to main dashboard title for cleaner layout
- Replace separate alert displays with color-coded row highlighting
- Add per-service disk usage collection using du command
- Update services widget formatting to handle small disk values
- Restructure into workspace with dedicated agent and dashboard packages

## Features
- Rotating host selection with left/right arrows (`←`, `→`, `h`, `l`, `Tab`)
- Live NVMe, service, memory, backup, and alert summaries per active host
- Live NVMe, service, CPU/memory, backup, and alert panels per host
- Health scoring that rolls CPU/RAM/GPU pressure into alerts automatically
- Structured logging with `tracing` (`-v`/`-vv` to increase verbosity)
- Help overlay (`?`) outlining keyboard shortcuts
- Config-driven host discovery via `config/dashboard.toml`
