fix(gateway): strip server-owned metadata from run input todos and goal (#7803 follow-up) (#7904)
* fix(gateway): strip server-owned metadata from run input todos and goal (#7803 follow-up)

Commit 459fc8c introduced shape validation for caller-written todos in
both strip_server_owned_state_metadata and normalize_input, but only
applied _strip_external_metadata_from_message_like in
strip_server_owned_state_metadata.

External callers submitting POST /runs or POST /threads/{id}/runs with
input.todos or input.goal could supply forged server-owned metadata
(such as untrusted_input: False, original_user_content, or artifact
knowledge_sources) directly into the agent graph.

Apply _strip_external_metadata_from_message_like to both normalized
todos and goal in normalize_input when trusted_internal=False.

* fix(gateway): mirror normalized goal and todos into canonical run record input

* fix(gateway): replace non-dict additional_kwargs and cover edge cases

- Ensure non-dict additional_kwargs in message-like entries is replaced with an empty dict instead of surviving the strip
- Remove redundant None-check on normalized_goal in normalize_input
- Add regression tests covering non-dict additional_kwargs replacement and untrusted_input stamping on human-like entries

* test(gateway): format todo input validation cases
