refactor: remove key transformation and align models with camelCase API responses

Remove the _transform_keys_in_data function from MlbDataAdapter that was
lowercasing all API response keys. Models now directly use the camelCase
field names returned by the MLB Stats API.

Key changes:
- Remove _transform_keys_in_data() function and its usage
- Update model field aliases to match actual API camelCase format:
  * homeRun, tieBreaker, isHomeRun, isTieBreaker (homerunderby)
  * dateTime, timeStamp, metaData (game models)
  * inTieBreaker, tieBreakerNum (homerunderby status)
  * wobaCon (stats)
- Make optional fields that may be missing in API responses:
  * calendar_event_id, start_time_tbd (game models)
  * wildcard_games_back, wildcard_elimination_number (standings)
- Update external tests to use camelCase field names
- Remove all mock tests and associated JSON fixtures (22,370 lines)

This simplifies the codebase by removing an unnecessary transformation
layer and ensures models directly reflect the API's native response format.
