Description

This PR addresses issue #1211 by converting hardcoded GitLab constants into settings that users can modify through a new settings form in the Account section.
Key changes include:

Created a new settings Redux slice to manage GitLab configuration

• Added persistent storage of settings using localStorage
• Replaced direct constant usage with getter functions throughout the codebase
• Implemented a settings form UI in the Account section
• Updated tests to use mocks for the new constant getter functions

These changes allow users to customize:

• GitLab group name (GROUP_NAME)
• Digital Twin directory (DT_DIRECTORY)
• Common library project ID (COMMON_LIBRARY_PROJECT_ID)
• Runner tag for CI execution (RUNNER_TAG)

---

Testing

• Added unit tests to verify the settings slice functions correctly
• Updated existing tests to use the new constant getter functions
• Manually tested the settings form to ensure values persist between sessions
• Verified that changes to settings properly affect GitLab operations

---

Impact

• Improves flexibility by allowing users to customize GitLab interactions
• Enhances user experience by providing a UI to modify these settings
• Helps with different GitLab configurations without code changes
• Settings are immediately applied after saving

---

Additional Information

The settings form includes a reset to defaults option in case someone need to revert their changes.

Checklist

• I have added tests for all the new code and any changes made to existing code.
