[user_accounts] Fix permissions visibility for unlinked modules

[arnav-makkar]

Brief summary of changes

Includes permissions that are not linked to any module by adjusting the WHERE clause to allow NULL active states.
This ensures all permissions appear on the frontend even if they don't have an associated module.

Test failure was expected after the initial query fix.

Previously WHERE m.Active='Y' made the LEFT JOIN on modules behave like an INNER JOIN, so permissions with no matching module row were silently dropped.

After changing to WHERE (m.Active='Y' OR m.Active IS NULL), those permissions are correctly included again. The unit test fixture contains such a case, so testGetPermissionsVerbose() had to be updated to match the corrected output.

All tests pass now, ready for review!
