Reorganize dashboard UI with tabbed layout and improved status bars

Add tabbed navigation in right panel with "hosts | services" tabs to
better utilize vertical space. Hosts tab displays all available hosts
with blue selector bar (j/k navigation, Enter to switch). Services tab
shows services for currently selected host.

Status bar improvements:
- Move dashboard IP to top-right status bar (non-bold)
- Restructure bottom status bar with right-aligned build/agent versions
- Fix overflow crashes using saturating_sub for small terminal windows

Additional changes:
- Add HostsWidget with scroll handling and mouse click support
- Bold styling for currently active host
- Create render_content() methods to avoid nested blocks in tabs
- Display SMB share read/write mode in share listings
