v2.51.5

Four fixes, no new surface.

• External units created by an integration keep a bare host, so they can be edited and set as the gateway again (#1968, reported by @harpyeagle in #1056).
• A Proxmox host and its untagged guests no longer show another client's VLAN (#1757, @MassiPi).
• One unit is one SSH connection again, instead of two (#1893, @crowedavid).
• An unknown uptime shows "—" instead of a real-looking "0d 0h" (#55, @harpyeagle).

Thanks

• @crowedavid for #1893, #1894, #1899, #1944, #1945, #1947 and #1949, seven reports that turned into fixes in this release.
• @MassiPi for #1757, the VLAN work that keeps improving the panel and the topology.
• @mgrupenhoff for #1943, the iOS standalone layout.
• @harpyeagle for #55 and the OPNsense reports in #1056.
