Full rewrite of devshell

migrates pre-commit to cachix's pre-commit-hooks

adds a ton of new hooks:
- check-added-large-files
- check-case-conflicts
- check-json
- check-merge-conflicts
- detect-private-keys
- fmt-check
- nil
- no-commit-to-branch
- statix (disabled for now)

migrates devshell to new devshells, set up modularly to have separate
functionality for sops, pre-commit-hooks, and our custom packages
