fix: resolve permission fallback bug, remove debug code, and cleanup duplication

Logic Errors
------------
- Sidebar: fix permissions fallback so a user with no permissions gets
  zero access instead of falling back to the full nav list
  (user?.permissions ?? [] instead of ?? navSections.flatMap(...))
- carMaintanance.service / UseCarsMaintanance: add pagination to the
  maintenance records fetch instead of loading the entire list at once
- api.ts: redact sensitive fields (password, token) before logging the
  request body in console.debug, to avoid leaking credentials/PII

Code Flow Problems
-------------------
- OrderFormModal: remove leftover console.log/debug statements and the
  redundant onClick handler on the submit button
- auth: remove the unused src/service/auth.service.ts (axios) and keep
  only src/services/auth.service.ts (fetch); fix useAuth.ts import path
  from

app/dashboard/roles/page.tsx
