feat(integrations): Propagate ViewerContext in Jira Server webhook (#112411)

## Summary
- Wraps the per-org iteration in `handle_status_change` with
`webhook_viewer_context` so downstream code has access to the current
organization identity via the ViewerContext contextvar.
- Gated behind the `viewer-context.enabled` option (no-op when
disabled).
- Part of the ViewerContext RFC rollout for webhook handlers.
