Add server-side pagination to dashboard API

Implement proper server-side pagination for the dashboard projects endpoint.

Current query fetches all projects which is O(n) with no upper bound. Need to:

  1. Add LIMIT/OFFSET to query
  2. Add compound index on (user_id, created_at)
  3. Update API response format to include pagination metadata
  4. Update frontend to use cursor-based navigation

Acceptance Criteria

  • API accepts page and limit query params
  • Default limit is 20, max is 100
  • Response includes total count and pagination metadata
  • Database query uses LIMIT/OFFSET
  • Dashboard loads in <1s for all users
