feat(assets): add job_ids filter to GET /api/assets (#13998)

* feat(assets): add job_ids filter to GET /api/assets

Mirrors the existing cloud `job_ids` query param on the local Python server:
clients can pass a comma-separated list (or repeated query params) of UUIDs
to filter assets by their associated job.

The `AssetReference.job_id` column already exists, so no migration is
needed — this just plumbs the filter through schema → service → query.

Marks the parameter as available in both runtimes by dropping the
`[cloud-only]` description prefix and the `x-runtime: [cloud]` tag from
the OpenAPI spec, per the OSS field-drift convention (absent runtime tag
= populated by both local and cloud).

* fix(assets): tighten job_ids — array schema, max_length, narrow except

From cursor-reviews on the parent commit:

- OpenAPI: declare job_ids as `type: array, items: string format: uuid`
  with `style: form, explode: true` so it matches the documented
  contract (and matches sibling include_tags/exclude_tags shape).
  Description now states both accepted shapes explicitly.
- Schema: cap `job_ids` at 500 entries (max_length on the Pydantic
  field) so a client can't splice an unbounded list into the IN clauses.
- Schema: drop `AttributeError` from the except — `raw` only contains
  `str` items by construction, so `uuid.UUID(<str>)` raises `ValueError`
  exclusively; the second clause was dead code.

* fix(assets): tighten job_ids validator + add schema-level tests

Aligns with the parallel hardening from draft PR #13848 (now closed as
a duplicate). The validator now:

- Raises ValueError on non-string list items (was: silently dropped).
- Raises ValueError on non-string / non-list top-level values like dict
  or int (was: silently passed through to Pydantic's downstream coercion).

Adds tests-unit/assets_test/queries/test_list_assets_query.py covering
the validator end-to-end: CSV canonicalization, dedup order, default
empty, invalid UUID, non-string list item, non-string non-list value,
and the max_length=500 boundary.

* feat(prompt): enforce canonical UUID prompt_id at job creation

POST /prompt previously accepted any client-supplied prompt_id verbatim,
str()-coercing even non-strings, and minting the literal job id "None"
for an explicit JSON null. The new GET /api/assets job_ids filter matches
stored job ids as canonical UUIDs exactly, so a non-UUID id minted a job
whose assets could never be filtered.

- validate_job_id (comfy_execution/jobs.py): requires a string in the
  canonical lowercase hyphenated UUID form; raises ValueError otherwise,
  including parseable-but-non-canonical spellings (uppercase, braced, URN,
  bare hex), which would otherwise be silently rewritten and then miss
  every exact-match lookup downstream (history keys, websocket
  correlation, /interrupt, the assets job_ids filter).
- POST /prompt: absent or null prompt_id means the server mints uuid4;
  invalid means 400 invalid_prompt_id on the standard error envelope.
- openapi.yaml: document the request-side prompt_id (format uuid,
  nullable) on PromptRequest.
- tests: unit matrix for validate_job_id; integration tests against the
  booted server covering rejection, acceptance, and null handling.
