Proxmox already runs vzdump backups, but nothing in the app said
whether they were actually succeeding — a silent backup failure is
one of the more dangerous blind spots a homelab admin can have. Adds
a "Backups" card to the Proxmox page: configured backup job
schedules (storage target, which guests, enabled/disabled) from
GET /cluster/backup, and recent vzdump task history per node from
GET /nodes/{node}/tasks?typefilter=vzdump, with a banner at the top
if the most recent run didn't succeed.
New "Proxmox backup failed" notification toggle under Settings ->
Notifications, on the same daily schedule as the other checks. The
scheduler checks each node's own most-recent vzdump run independently
(not just the single most recent task overall) so one node's healthy
backup can't mask another node's failing one in a multi-node cluster.
Known limitation, documented in the adapter's own header comment:
Proxmox's task list doesn't reliably expose which specific guest
failed within an "all guests" job — only the task's own log text has
that — so this surfaces job- and task-level status rather than
guessing at per-guest outcomes.
Verified against a fake Proxmox server (real self-signed HTTPS, since
the adapter's node:https usage can't be monkey-patched under ESM)
reproducing the documented /cluster/backup and task-list response
shapes: job parsing (all-guests+exclude vs specific-vmids+disabled)
correct, task OK/failure parsing correct, and the critical multi-node
scenario confirmed — one node's failing latest run flagged, the
other's healthy latest run correctly left alone, with exactly one
notification of the right content. This reproduces Proxmox's
documented API shape rather than a live-verified one; flag if the
real cluster's response differs in some way this didn't anticipate.
Confirmed the real dev database's mtime was untouched throughout.
