feat(cdk): add token_prefix support to SessionTokenAuthenticator

This adds a token_prefix field to SessionTokenRequestApiKeyAuthenticator
that allows prepending a custom prefix to the session token when injecting
it into requests.

This is useful for APIs that require a specific prefix before the token,
such as Django REST Framework APIs that expect 'Authorization: Token <value>'
format instead of the standard Bearer format.

Changes:
- Add token_prefix field to SessionTokenRequestApiKeyAuthenticator in schema
- Create PrefixedTokenProvider wrapper class in token_provider.py
- Update factory to wrap token provider with prefix when token_prefix is set
- Regenerate Pydantic models from schema
- Add unit tests for PrefixedTokenProvider

Closes #884
