Implement pre-commit hooks.

[owenlittlejohns]

Description

This is analogous to the HOSS PR adding pre-commit hooks to this project. It adds:

• Trailing whitespace
• Blank lines at the end of the file.
• Valid JSON and YAML syntax.
• ruff linting.
• black code formatting.

Note, these should only run on files that are touched in a commit.

Jira Issue ID

N/A - IP-sprint activity.

Local Test Steps

• Pull this branch.
• Follow the new instructions in the README, including the optional pre-commit run --all-files.
• To really test this, make some minor change, use git add then git commit. You should see the checks all run when you are trying to use git commit.

PR Acceptance Checklist

• Jira ticket acceptance criteria met.
• CHANGELOG.md updated to include high level summary of PR changes.
• docker/service_version.txt updated if publishing a release.
• Tests added/updated and passing.
• Documentation updated (if needed).

As with the other PR, I ran everything but black over --all-files. These are things that ruff picked up for us.
