Improve dashboard display and fix service issues

- Remove unreachable descriptions from failed nginx sites
- Show complete site URLs instead of truncating at first dot
- Implement service-specific disk quotas (docker: 4GB, immich: 4GB, others: 1-2GB)
- Truncate process names to show only executable name without full path
- Display only highest C-state instead of all C-states for cleaner output
- Format system RAM as xxxMB/GB (totalGB) to match services format
