Dev: Migrate to uv

[conbrad]

This PR migrates the backend Python project from Poetry to UV and restructures the codebase into a monorepo with separate packages. Uses a single virtual env, backend/.venv/. Setup to install and run has been updated and instructions found in backend/packages/wps-api/README.md.

Package Management

• Migrated from Poetry to UV for faster dependency resolution and installation
• Created workspace configuration with 4 Python packages: wps-api, wps-shared, wps-jobs, wps-tools
• In a follow up PR I'll move the sfms package (code for SFMS windows box).

Code Restructure

• Moved api/ directory contents to backend/packages/wps-api/, similar for wps-shared, wps-jobs, wps-tools
• Configured package structure for all packages with src/ layout based on: https://docs.astral.sh/uv/concepts/projects/workspaces/#workspace-layouts

CI/CD Updates

• Updated all GitHub Actions workflows to use UV instead of Poetry
• Added test-wps-jobs job to integration and post-merge workflows
• Updated all Docker builds to use UV
• Updated OpenShift deployment templates

Changes

• Adjusted test tolerances (this seems to flip/flop a lot so I increase the tolerance):
  • uv vs poetry dependency resolution leading to slightly different package versions
• Adjusted README documentation to account for setup, including brew install uv for mac.sh.
• Local Dockerfile for local dev uses simpler app startup command

Testing

• All existing tests pass with the new structure
• Coverage reporting now works for all packages separately
• CI pipeline validates all packages independently
• Manually kicked off ecmwf job with oc create job -n e1e498-dev "ecmwf-1" --from=cronjob/ecmwf-wps-pr-4912 to verify herbie works, let other jobs run overnight.
• Manually kicked off SFMS nats consumer processing with tif_pusher script (in new package with uv run --package wps-tools python -m wps_tools.tif_pusher 2025-06-24 2025-06-25) to verify SFMS tifs are processed

Closes #4903

Could shared dependencies like pytest, ruff, coverage, etc be installed here in a central location?
