Phase 0: Remove plan operation limit fields (credit-only system)

- Removed all operation limit fields from Plan model
- Kept account management limits (max_users, max_sites, etc.)
- Updated PlanSerializer to remove limit fields
- Updated PlanAdmin to remove limit fieldsets
- Created migration to remove limit fields from database
- Plan model now only has credits, billing, and account management fields
