refactor(routes): Phase 3.1 - standardize services.js with explicit dependencies

- Replaced god object ctx with explicit dependency injection
- Added JSDoc documenting all required dependencies
- Updated response calls to use response-helpers (success/error)
- Maintained all existing functionality
- Self-documenting: you can see exactly what this route needs
- Easier testing: mock only what's actually used (14 deps vs 50+ ctx properties)
