fix: category cache refresh, API 404, redundancy mapping, cost/relation authz, voterToken exposure

- Invalidate categories/features queries after creating/editing tools so new
  categories appear immediately in search, browse dropdown and tool form
- Always refetch categories/features when the combobox/suggestion inputs mount
- Return JSON 404 for unmatched /api routes instead of the SPA index.html
- Read the manually confirmed 'better tool' from the recommendation notes
  instead of using the min tool id in the redundancy dashboard
- Require admin for cost/relation update+delete endpoints
- Stop exposing the voter token in the ratings list response
- Fix parseInt type error on user id params (Express 5 params typing)
