Enhance User Profile Overview with Commits and Activity Reporting

What does this MR do?

This merge request enhances the User Profile Overview in the GitLab Compliance Checker by adding a working commits tracking feature and a detailed activity report view.

It enables the application to:

• Reliably fetch user commits from GitLab (project-wise)
• Display commits with date, time, and working-hour classification
• Lay the foundation for a detailed activity report dashboard covering commits, issues, merge requests, and projects

This improves visibility into actual user contributions, beyond just summary counts.

Motivation / Use Case

Previously, the dashboard only showed aggregate counts (projects, issues, MRs), and commits were either missing or unreliable due to GitLab API constraints.

As a mentor/admin, it is important to:

• Verify when and how actively a user is contributing
• Track work during defined working hours
• Review detailed contribution data when needed

This feature addresses that gap by providing accurate commit-level insights and a pathway to detailed reporting.

Implementation Notes

• Commits are fetched project-by-project using the GitLab API (/projects/{project_id}/repository/commits), which is the only reliable approach on the target GitLab instance.

• Commit data is processed to extract:

  • Commit message
  • Date
  • Time

• Commits are classified into working-hour slots:

  • Morning: 09:00–12:00
  • Afternoon: 14:00–17:00

• Only commits within these slots are displayed in the UI.

• The implementation is read-only and does not introduce any breaking changes.

• Existing dashboard features remain fully backward compatible.
