Add experiment_enabled field to PR review payloads sent to Seer. The field indicates whether an organization is enrolled in code review A/B testing experiments, controlled by the feature flag organizations:code-review-experiments-enabled. Changes: - Add experiment_enabled bool field to SeerCodeReviewRequestForPrReview - Conditionally include experiment_enabled in payload for PR review requests only - Add type annotation to prevent mypy errors when adding bool to dict - Add comprehensive test coverage using @with_feature decorator The field is only included for pr-review request types, not pr-closed, allowing Seer to apply different experimental behaviors based on the assignment.

## Summary
Adds experiment assignment to code review payloads sent to Seer. This
allows Seer to apply different experimental behaviors (e.g., different
prompts, features) based on whether an organization is enrolled in A/B
testing experiments.
## Changes
- Add `experiment_enabled` field to `SeerCodeReviewRequestForPrReview`
model
- Conditionally include `experiment_enabled` in payload for PR review
requests only (not PR closed)
- Add explicit type annotation to prevent mypy errors
- Add comprehensive test coverage using `@with_feature` decorator
## Implementation Details
The monolith checks the feature flag
`organizations:code-review-experiments-enabled` and includes the boolean
flag in the request payload sent to Seer. The field is only included for
`pr-review` request types, not `pr-closed` events.
**Payload structure:**
```json
{
"request_type": "pr-review",
"external_owner_id": "...",
"data": {
"repo": {...},
"bug_prediction_specific_information": {...},
"config": {...},
"experiment_enabled": true // <-- New field
}
}
```
