feat!: rename CartesiaExperimentalControlsSpeedZero and FallbackAzureVoiceVoiceIdZero enums

Two public enum classes have been renamed for consistency. Existing
code referencing the old names will fail with a class-not-found error
and must be updated to use the new names.

Key changes:
- Rename `CartesiaExperimentalControlsSpeedZero` → `CartesiaSpeedControlZero`
- Rename `FallbackAzureVoiceVoiceIdZero` → `FallbackAzureVoiceIdZero`
- Update PHPDoc annotations in `CartesiaExperimentalControls` and `FallbackAzureVoice` to reference the new enum names
