fix: correct API method calls in AdminTrainingProfiles (#15)

Fixed "U.get is not a function" error:
- Added missing API methods to api.js:
  - getProfileStats()
  - getProfileTemplates()
  - applyProfileTemplate()
  - getTrainingParameters()
  - batchEvaluateActivities()
- Updated AdminTrainingProfiles.jsx to use correct methods
- Replaced api.get/post/put with specific named methods

Error resolved. Page should now load correctly.
