Move jobs to jobs folder

**Describe the task**
Move cronjobs to jobs folder, so we know where to look for jobs.

**Acceptance Criteria**
- [ ] api/app/weather_models/env_canada.py -> api/app/jobs/env_canada.py
- [ ] api/app/c_haines/worker.py -> api/app/jobs/worker.py (c_haines_worker.py?)

**Additional context**
- Add any other context about the task here.
- Or here

Start with api/app/weather_models/env_canada.py and api/app/c_haines/worker.py, then search the repository for imports and references to both cronjobs. Move the files into api/app/jobs with the intended worker filename, update references, and verify that the application still discovers and runs both jobs.
