Reads files the backup user can't see from the host (container-owned, e.g.
Nextcloud's www-data data dir) by streaming them out THROUGH the container
(docker exec tar) — no host root, no host read perms, works rooted + rootless.
Extracts to staging as plain files so restic keeps full dedup + per-file
restore (not a piped tar blob); the live path is excluded from the snapshot.
Restore streams the staging copy back through a throwaway in-namespace
container that recreates the tree with the app's uid:gid.
Declared via a libreportal.backup.files compose label; Nextcloud (html, 33:33)
is the first to use it. Live capture failure falls back to stop-snapshot-start.

Live-restore of a server DB (MariaDB/Postgres) raced the engine's first-init:
it starts a throwaway temp server, runs setup, then restarts the real one. The
old ping-based readiness passed against the temp server and the load hit the
restart, failing once.
- _backupDbWaitReady now requires a real query to succeed on two consecutive
checks, so the restart breaks the streak and we only proceed once the real
server is stably up.
- The dump load is retried (idempotent — the dump drops+recreates each object)
to ride past a final init bounce.

Adds CFG_<APP>_BACKUP_STRATEGY (default auto) so an app's backup strategy can
be overridden from its Advanced config tab, taking precedence over the global
default. Added to the 10 live-capable apps, so the dropdown's 'live' option only
appears where it actually works.
- backupResolveStrategy now checks the per-app override before the global value.
- backupAppLiveCapable / backupAppStrategyOptions expose capability + the valid
option set; predicate helpers hardened with explicit returns so they behave
identically with or without shell errexit.
- BACKUP_STRATEGY field mapping (select, advanced) renders the dropdown.

- Add libreportal.backup.db labels to the MariaDB/Postgres apps (nextcloud,
owncloud, bookstack, mastodon, invidious) so they back up live + consistent.
- If a declared dump cannot be taken (DB down, wrong path), the backup falls
back to stop-snapshot-start for that run instead of snapshotting torn data —
a misconfiguration degrades to 'safe with downtime', never to 'unsafe'.

Adds a logical-dump path so apps with a database can be backed up with zero
downtime and full consistency, instead of stopping the container.
- backup_db.sh: dump each declared DB live (mysqldump --single-transaction /
pg_dump / sqlite3 .backup), exclude the raw data dir from the snapshot, and
replay the dump on restore (pre-start rehydrate for sqlite, post-start load
for server engines).
- Databases are declared via a 'libreportal.backup.db' compose label so the
metadata travels with the app in the snapshot.
- New 'auto' strategy (now the default): live where a DB is dumpable or the app
is marked live-safe, stop-snapshot-start otherwise. Explicit stop/pause/live
remain as overrides.
- restic/borg/kopia adapters honour an exclude list on the live path.
- Manifest records the resolved per-app strategy and dumped databases.
