Fix Cronicle event: use HTTP plugin (no shell needed) and every-minute timing

- Switch shellplug → urlplug to avoid spawn errors in shell-less containers
- Explicitly set timing to all 60 minutes (Cronicle {} defaults to hourly :00)
- Restore RAGGR_INTERNAL_URL env var for the HTTP plugin target URL

Delete the existing broken Cronicle event before redeploying so it gets recreated.
