Adds packaging and continuous integration (CI) support

[guoguojenna]

This pull request adds packaging and continuous integration (CI) support for the configshell-fb project, along with minor code maintenance. Here’s a summary of the key changes:

1. Packaging and CI configuration added:

• Introduces .packit.yaml for Packit automation, enabling COPR builds, tests, and Fedora/EPEL sync.
• Adds fedora/python-configshell-fb.spec for RPM packaging in Fedora.
• Adds .fmf/version and ci-tests/sts.fmf for tmt test plan import.
• Added a new GitHub Actions workflow for CodeQL analysis, which runs security and quality checks on Python code for pushes, pull requests, and on a weekly schedule.

2. Pre-commit enhancements:

• Updates ruff-pre-commit from v0.7.1 to v0.11.11.
• Adds packit/pre-commit-hooks for Packit config validation.
• Updates pre-commit hook list—removes duplicates and improves formatting.
• Adds pre-commit.ci configuration for automated fixes and monthly updates.

3. Python module cleanup:

• Updates all in configshell/init.py to fix the order and content of exported symbols.
