- separate caching into restore and save step
- always save cache even if build failed (speeds up next attempt)
- use build plan rather than freeze file as cache key

Pull request overview
This PR updates the CI infrastructure to use the latest versions of GHC, Cabal, GitHub Actions, and Python dependencies. The caching strategy is modernized to use separate restore and save steps with build plan-based cache keys instead of freeze files.
- Modernized CI caching by splitting cache restore/save steps and using plan.json instead of freeze files as cache keys
- Updated GHC versions (9.6.7, 9.8.4, 9.10.3, 9.12.2) and Cabal to 3.14.2.0
- Migrated to fix-whitespace-action and separated test targets in Makefile
