Update test infrastructure to use register_actions hook

- Consolidated register_permissions and register_actions hooks in my_plugin.py
- Added permission_resources_sql hook to provide SQL-based permission rules
- Updated conftest.py to reference datasette.actions instead of datasette.permissions
- Updated fixtures.py to include permission_resources_sql hook and remove register_permissions
- Added backwards compatibility support for old datasette-register-permissions config
- Converted test actions (this_is_allowed, this_is_denied, etc.) to use permission_resources_sql
