fix(main): add ci-canary.yml + disable pr-auto-scan schedule on main

- Copy ci-canary.yml from develop (PR #1636) to enable 30-min health checks on main
- Disable pr-auto-scan.yml schedule on main (was still running */15, causing failure spam)
- Relates: PR #1635 (develop already had schedule disabled)
