fix(monitor): handle a PBS on the same host and complete the PBS views

- Open a PBS installed on this host on the address in use, without probing it
- Never carry or offer localhost addresses between Monitors
- Read the PBS of a PVE+PBS host in Backup Server, with its hostname and version
- Offer the PBS storages without a connection, with address and fingerprint
- Show the disks and pools of a PBS in its Datastores tab
- Hide guest and PVE storage settings on a PBS
- Show a clearer status line for a PBS
