Catch domain-level ValueErrors in asset_state_store route handlers and translate them to HTTP 400 Bad Request errors. Previously, these were unhandled and surfaced as HTTP 500 Internal Server Errors, leaking internal traces.

This implements the same exception translation pattern already established in task_state_store.py.

Hi Team,
This PR is ready for review. All core, DB (Postgres/MySQL/SQLite), and integration tests are passing cleanly.

The single failure in the Static checks job appears to be caused by a transient prek hook cache issue on the runner (insert_license: No such file or directory). Could a maintainer please trigger a quick re-run for that job when taking a look?

Thanks!
