Services could not carry hostnames through cast: `desiredFromManifest`
dropped a service's `domains` and warned they were a manual Coolify UI act,
citing a re-checked "no flat `domains` on a 4.1.2 service, on any route."
The audit (#72) disproved that — the same failure mode #51 corrected for
backup schedules. The FLAT shape genuinely has no route; the per-container
CAPABILITY was there at 4.1.2 all along.
`POST /services` and `PATCH /services/{uuid}` both take a `urls` list
([{name, url}], url comma-joined) that `applyServiceUrls` matches to a
`ServiceApplication` by name and stores as its `fqdn`; `GET /services/{uuid}`
loads `applications` and returns each `fqdn` (verified against
ServicesController v4.1.2). So services now speak the SAME per-container
vocabulary a dockercompose app does:
- **Manifest:** `service_domains: { <container>: [url] }` replaces the flat,
unhonorable `domains` on a service (a flat list cannot name which container
a hostname belongs to — exactly what `urls` requires). Canonicalized (keys
and each URL array sorted) so container order never false-drifts.
- **Write:** `serviceApiFields` builds `urls` on create and update.
- **Read/diff:** a supplementary `GET /services/{uuid}` per service
(`attachServiceDomains`, gated to `diff`/`apply` like backups) projects
`applications[].fqdn` back into `service_domains`, so a declared hostname is
compared every run — no perpetual drift, no manual UI step.
- **Pre-flight:** a service create's `service_domains` joins
`desiredDomainsOfCreate`, the more important because a service create whose
domain conflicts is DELETED server-side before the 409 (rollback).
Two limits stated out loud: the read is fail-closed (an unreachable/
unrecognized `GET /services/{uuid}` aborts rather than projecting empty and
re-PATCHing forever), and `inventory --emit-draft` does not yet make the
per-service GET, so a drafted service's hostnames are still declared by hand
(same as backups) — draft/semantics say so.
