Two separate bugs found while testing the Audit/Details UI against a
real k8s-format backup (myapps-k8s-backup-*):
1. Format-hardcoded checks. audit_backup()'s Internal Structure and
Volume Count checks assumed the legacy Docker-era archive layout
(volumes/*.tar.gz, compose-files/) and would fail every k8s-format
backup (per-app dirs with manifests.yaml/db-dump.sql.gz/pvc-data.tar.gz)
even when it's perfectly healthy - same root cause as the
myapps-backup-*/myapps-k8s-backup-* prefix bug fixed earlier, just in
the audit checks instead of the listing/delete glob. cloud_backup.py's
r2_audit_backup() had the identical unpatched filename regex, and
app.py's /api/backups/details route had its own, which outright
400'd any k8s-format filename before even looking at it.
2. A bigger, separate bug this surfaced: get_local_backups(),
get_vm_backups(), and _resolve_archive_path() all branch on
RUNNING_ON_MAIN_SERVER to decide between direct filesystem access and
SSH-to-self - and from inside the management-platform pod that flag's
hostname check can be wrong for the pod's own ephemeral hostname
depending on how it's evaluated, sending these down the SSH branch
using a topology (separate warm-standby-on-the-VM SSH path) that
doesn't apply to a pod that already has /root hostPath-mounted in.
Fixed by trying direct filesystem access first wherever the archive
would already be locally reachable, falling back to the existing SSH
paths otherwise - this preserves the original warm-standby-on-VM
failover design (a real second deployment of this platform on the VM
host, kept reachable via SSH when the main server is down) completely
unchanged; it only adds the fast local path for the case where the
caller already has direct filesystem access.
Verified against both a real k8s-format backup (odoo, single-app) and a
real legacy-format backup on disk - both audit correctly now, with
format-appropriate checks and labels.
