Apps can now declare a setting with "type": "path" whose value is an
absolute host filesystem path. Compose bind-mounts it via standard .env
substitution (${MEDIA_PATH}:/media) — no reconciler changes needed.
Unlocks media/data-heavy apps (Jellyfin, later Paperless, Nextcloud,
Immich) that point at existing user data instead of copying it into a
Docker volume.
Install/update refuses values that aren't absolute, don't exist, aren't
directories, or resolve into a system-path deny-list (/, /etc, /root,
/boot, /proc, /sys, /dev, /bin, /sbin, /usr/bin, /usr/sbin,
/var/lib/furtka). Path.resolve() is applied before the deny-list check
so /mnt/../etc traversal is caught too. Error messages surface in the
existing install/edit modal.
UI: path settings render as a text input with a /mnt/… placeholder.
The manifest's `description` field carries the actual hint ("Absoluter
Pfad zu deinem Filme-Ordner, z.B. /mnt/media"). No new form
components, no new API routes.
Tests: 9 new cases for install + update path validation; 1 new case
for manifest schema accepting the path type. 211 total passing.
