test: use unique library name and path in tests

Avoid UNIQUE constraint conflicts on library.name and library.path when
running tests in parallel. Both playlist_repository_test.go and
tag_library_filtering_test.go now generate timestamp-based unique
suffixes for library names and paths to ensure test isolation.
