feat: support query parameters for list audit API

[chlins]

This pull request enhances the audit functionality by introducing support for query parameters in the GetAudits endpoint, improving the filtering and sorting of audit records, and updating the corresponding test cases. Below are the key changes:

Enhancements to Audit Query Functionality:

• Updated the GetAuditsQuery struct in manager/types/audit.go to include new fields (ActorType, ActorName, EventType, Operation, State, Path, and StatusCode) for filtering audit records. Each field has validation rules for allowed values and formats.
• Modified the GetAudits method in manager/service/audit.go to apply filtering based on the new query parameters and to sort results by created_at in descending order.

Test Case Updates:

• Added a new test case in manager/handlers/audit_test.go to verify the GetAudits endpoint's behavior when query parameters are provided. This test ensures correct filtering, pagination, and response structure.
