chore: expand JSDoc for regex pattern field on structured output types

Add detailed documentation to the `regexPattern` field across
`CreateStructuredOutputDto`, `UpdateStructuredOutputDto`, and
`StructuredOutput` explaining how simulation evaluations build their
canonical transcript and how that differs from production-call and
call-preview extraction.

Key changes:
- Document simulation transcript format (User:/AI: dialogue, tool_calls, tool_call_results) in `CreateStructuredOutputDto.regexPattern`
- Add the same expanded JSDoc to `UpdateStructuredOutputDto.regexPattern`
- Add the same expanded JSDoc to `StructuredOutput.regexPattern`
