fix(wireless): prune interfaces deleted on the device; collect wireless on full sync (v0.17.5-beta)

Resolves #87 — virtual APs removed directly on the device (WinBox/WebFig) kept
showing in the radios/interface lists, and neither refresh button cleared them.

Two distinct bugs:

1. Stale rows. The collectors upsert every interface found on the device but
   never removed rows for interfaces that disappeared, so deleted radios lingered
   forever. Added a prune to collectWirelessInterfaces, collectInterfaces (same
   bug for deleted VLANs/bridges/bonds) and collectSecurityProfiles, deleting
   stored rows whose names are no longer present on the device.

   Safety: the prune only runs when the device list was fetched successfully.
   Fetches that previously swallowed errors into an empty array now return null
   and skip the prune, so a transient API failure can never be mistaken for
   "everything was deleted". /interface/print already throws on failure.

2. Full sync skipped wireless entirely. collectAll() — what POST /devices/:id/sync
   runs — never called collectWirelessInterfaces/collectSecurityProfiles, so a
   manual resync could not refresh radios or clear stale ones; only the 5-minute
   slow poll touched them. collectAll now collects wireless data for wireless_ap
   devices, making the fix reachable on demand.

Verified on a live hAP-class AP: injected a ghost virtual-AP row, ran a sync, and
the ghost was removed while all 7 real interfaces (and offline devices' rows)
were retained. 114 backend tests pass.
