admin 6c1762141a v0.12.7: mandatory HDD backup, pre-dump, restore for all apps
Fix 1: HDD data backup is now mandatory for all deployed apps.
resolveAppBackupPaths() iterates ListDeployedStacks() directly — no
longer reads GetAppBackupMap() or checks the Enabled flag. DiscoverAppData()
drops backupPrefs parameter; BackupEnabled is set from HasHDDData.
Five dead settings methods removed: IsAppBackupEnabled, SetAppBackup,
GetAppBackupMap, SetAppBackupBulk, GetAppBackupPrefs.

Fix 2: Cross-drive backup now triggers a fresh DB dump (DumpStackDB)
before running. DBDumper interface added to crossdrive.go; Manager
implements it; SetDBDumper wired in main.go. Non-fatal — proceeds with
user data backup even if DB dump fails.

Fix 3: Restore dropdown shows ALL deployed apps (not just HDD+enabled).
restore.go rewritten: always restores config+DB, adds user data if hasHDD.
UI shows restore type banner (full / config+DB / config only) with
color-coded styling. Snapshot API clarified for non-HDD apps.

Fix 4: "Docker kötetek" → "Konfiguráció" — named volumes are not in
the restic backup paths; compose files + app.yaml are what's backed up.
