Migrate views from ds.permissions to ds.actions, refs #2528

Updates all permission debugging views to use the new ds.actions dict
instead of the old ds.permissions dict. Changes include:

- Replace all ds.permissions references with ds.actions
- Update field references: takes_database/takes_resource → takes_parent/takes_child
- Remove default field from permission display
- Rename sorted_permissions to sorted_actions in templates
- Remove source_plugin from SQL queries and responses
- Update test expectations to not check for source_plugin field

This aligns the views with the new Action dataclass structure.
