feat(admin): rename series route and add tags review page

Rename /admin/series-management to /admin/series so it follows the
/admin/<section> convention; the breadcrumb's auto-derived parent link
is now a real route (was a dead /admin/series link).

Add an /admin/tags page to review pending TagSuggestions — list,
approve (creates the Tag), reject — backed by new admin endpoints and a
tagSuggestionReviewSchema. Resolves the dead /admin/tags alert link.
