feat(code_review): Set context as tags

[armenzg]

Summary

Applies the same context extraction and Sentry SDK tagging pattern used in the seer repository to Sentry's code_review webhook handlers.

Changes

• utils.py: Added extract_webhook_context() to combine GitHub event info with Sentry-specific context (org, repo, integration, provider). Returns a dict suitable for sentry_sdk.set_tags().
• handlers.py: Call extract_webhook_context() and sentry_sdk.set_tags(context) at webhook entry so all downstream logs, errors, and spans get the context automatically.
• task.py: Extract context from the transformed payload and sentry_sdk.set_tags(context_tags) at the start of process_github_webhook_event() so the async task execution scope also has tags.

Pattern (from seer)

In seer's CodegenStep._invoke():

context = extract_context(self.context.request)
sentry_sdk.set_tags(context)

We now do the equivalent in both the webhook handler path and the Celery task path.

Benefits

• Automatic tag propagation to Sentry errors, transactions, and spans
• Better error grouping and debugging in Sentry UI
• Consistent pattern between seer and Sentry code_review

None values not filtered before setting Sentry tags

Low Severity

The context dict from extract_webhook_context() is passed directly to sentry_sdk.set_tags() without filtering None values. The extract_github_info() function returns a dict where most fields default to None, and extract_webhook_context() also sets sentry_integration_id to None when no integration is provided. In task.py, None values are explicitly filtered out with a comment stating "Filter out None values to avoid cluttering Sentry tags" - but this filtering is missing in handlers.py, causing inconsistent behavior.
