fix: enforce action availability and model access on the chat action route (#27243)
The chat action route loaded a Function by its raw action_id and executed its action callable after only checking that the id and the requested model existed. The model list that the client renders actions from resolves each model's actions to the active action-type Functions that are global or assigned to that model, and the action route did not mirror that resolution, so a disabled, unassigned, or wrong-type Function, or an action on a model the caller cannot access, could be reached by calling the route directly.

Gate the route on the same rules the model resolution applies: the Function must be an active action, and for server-resolved models the caller must have model access and the action must be one the model actually surfaces (matched by function id, the prefix of each model actions entry, so single and sub-actions both resolve). Direct connections carry a client-supplied model the caller already owns, so the model-bound checks are scoped to non-direct calls; the active-action check always applies. Executing admin-authored Function code remains intended behaviour — this only keeps the route consistent with which actions each model exposes.
