[management] Expose live model discovery on the provider API

Adds POST /api/agent-network/catalog/providers/models, so the provider
form can offer the models an operator's own credential can reach instead
of only the compiled-in catalog.

A caller names a catalog provider and supplies either the key they are
typing (the record does not exist yet) or the id of a saved record whose
stored credential should be reused — which lets the dashboard refresh a
list without ever holding the key. The two are mutually exclusive:
accepting both would run an arbitrary credential under the identity of a
record the caller may only be permitted to read. When a record id is
given, the catalog id and upstream come from the record too, so the
credential cannot be aimed at a different vendor's endpoint.

Gated on Create rather than Read. This spends the operator's credential
against a third party, which is not something a read-only role should be
able to make the server do.

A provider with no listing endpoint answers 422 rather than 500: the
caller falls back to the catalog's own models on that outcome, so it has
to be distinguishable from a failure.

The region is read back out of the configured upstream by matching it
against the catalog's host template, since a provider record has no
region field and the operator already encoded one when they set up
inference. An upstream matching no template is refused rather than
guessed at — a wrong region would dial another account's endpoint.

+      summary: Discover the models a provider credential can reach
+      description: |
+        Asks the vendor which models the supplied credential can actually use, so the provider form can offer a live list instead of only the static catalog. The endpoint, auth header and response shape are taken from the catalog entry, never from the request.
+
+        Supply either an api_key together with the upstream_url being configured (before the provider is saved), or a provider_id of an existing record to reuse its stored credential.
+
+        Returns 422 for a catalog provider that has no listing endpoint (most gateways); the caller should fall back to the catalog's own model list. A model whose price the shipped table does not know is returned with pricing_known false, and the operator must set rates for it.
