* fix types

* suppress mysql from show start trial modal

* Skip MySQL-incompatible tests for access control and channel banner features

Skip the following tests when running with MySQL database:
- Access control policy tests (create, get, delete, check/test expressions, search, assign/unassign, get channels)
- Channel banner tests in TestPatchChannel and TestCanEditChannelBanner

These features are not supported on MySQL and the tests would fail.
Tests will continue to run normally on PostgreSQL.

* Skip TestSearchChannelsForAccessControlPolicy subtest for MySQL

Add MySQL skip logic to the "SearchChannelsForAccessControlPolicy with regular user"
subtest as this access control feature is not supported on MySQL.
