The CheckSuiteID parameter was referencing a non-existent 'check_suite_id'
column in the action_run table. This commit removes the hallucinated database
schema reference while maintaining API compatibility.
Changes:
- Remove CheckSuiteID field from FindRunOptions struct
- Remove check_suite_id database query condition
- Remove parameter handling logic from shared action handler
- Remove related tests for non-functional feature
- Update Swagger docs to indicate parameter is not supported in Gitea API
- Maintain GitHub API compatibility by keeping parameter documented
The check_suite_id parameter is now silently ignored when provided,
with clear documentation that it's not supported in Gitea.
