Add dashboard IPs/restart/connections, SMB read-only and recycle bin

Dashboard:
- Server IPs card showing all non-loopback IPv4 interfaces
- Restart buttons next to smbd/nfsd status dots (POST /api/service/<name>/restart)
- Active SMB connections table (smbstatus -b parsed in backend)

SMB edit modal:
- Read only toggle (writable vs read only in smb.conf)
- Recycle Bin toggle (vfs objects = recycle, files go to .recycle folder)

Docs: PLANNING.md phase 3.5, README recycle bin + read-only, CLAUDE.md JS overview
