fix(roles): normalize cache keys and improve test coverage

Normalize permission search cache keys (trim + lowercase) so queries
like "Dataset", "dataset", and " dataset " share the same cache entry.
Stop clearing the search cache on empty searches so previously fetched
results remain available. Add tests for state isolation when switching
roles, variable page sizes, concurrency limits, and whitespace/case
normalization. Fix prettier formatting in RoleListEditModal useEffect
dependency array.
