ci: simplify Coolify deploy trigger to a single curl (#573)

## What

Replace the ~60-line bash retry loop in the deploy step with native curl
flags.

## Why

The old block reimplemented in shell what curl does natively (timeouts,
retries, error handling), plus manual body/timing parsing with a marker
separator.

- `--max-time 15` caps each attempt so the job can't hang for ~20 min on
an unreachable box.
- `--retry-all-errors` turns a timed-out attempt into the next retry (a
plain `--retry` doesn't always treat exit 28 as retryable).
- `--fail` keeps a webhook error (4xx/5xx) from passing the step
silently.

## Notes

- Now uses the `COOLIFY_WEBHOOK_URL` secret instead of
`DEPLOYMENT_TOKEN` + hardcoded uuid URL. **This secret must exist in
GitHub Actions before merge or the deploy breaks.**
- Drops the 10–20 min retry waits that gave a prior rebuild time to
finish. Fine if the webhook queues the deploy; add back if it rejects
requests during an in-progress rebuild.
