ombi: its config is placed, its image is the one ace runs

ombi's definition named /services/ombi/config (a HAL machine path) in three
places and pinned an image older than the one ace runs. Ombi migrates its
own SQLite schema, so a take onto the older pin (v4.53.10-ls267) would start
it on a database the newer build (ls269) already touched.

- config is a pathless placed directory, mounted as ${dir:config}
- a state directory placed at the assignment root carries route.json
- image pinned to the digest ace runs today (v4.53.10-ls269)
- the sidecar reaches ombi on the machine port the mesh assigns
  (${port:3579}) rather than assuming 3579 is free
- the sidecar no longer mounts ombi's data directory: MESH_OMBI_CONFIG_DIR
  is read by no code, and the mount exposed the databases for nothing

Verified: catalogue tests (MESH_CATALOGUE set, 6 pass, none skipped); the
pinned image starts as PUID 1000 in a 0700 dir and answers /api/v1/Status
200; data owned 1001:2000 (ace's media ids) under a 1000:1000 dir is
re-owned by the image's init and serves 200; a minted ApiKey is refused
(401) - the api-key secret must be accepted from ombi's own settings.
