test(dashboard): align test seed naming with the canonical Title-case set + fix stale expectations

The test helper createDefaultCollectionsForUser carried its own
kebab-case copy of the default system collections — drifted from the
canonical Title-case list the registration seed and
RestoreSystemCollection use. Every suite run against the shared dev DB
re-created a kebab set beside the canonical one (the duplicate sections
on the customize screens); the dev DB is cleaned and the helper now
uses the canonical list.

Two stale expectations corrected while re-running the suite:
TestGetSections_EndToEndFlow asserted the kebab ids (now asserts the
Title-case names — section ids ARE collection names), and
TestGetSections_MissingLibraryID expected a 400 the handler never
implemented — absent library_id is the All Libraries view by design
(now asserts 200 + aggregated sections).
