feat:Team analytics UI

What does this MR do and why?

This MR introduces a Team Analytics Dashboard in Streamlit that reads team configuration from a CSV file and displays GitLab analytics at both team and individual levels.

Key Features:

• Upload a CSV file containing:

  • team_name
  • username (GitLab usernames)

• Displays:

  • Team-level totals:
    • Commits
    • Merge Requests
    • Issues
    • Projects
    • Groups
  • Individual-level stats for each team member

• Adds a Date Filter (Start Date / End Date) that:

  • Filters commits, merge requests, and issues
  • Applies to both team and individual views

• Implements:

  • Section-wise loading (Commits, Issues, MRs load independently)
  • Proper st.session_state handling
  • st.cache_data(ttl=300) for optimized API calls
  • Clear Filter button that resets:
    • Dates
    • Cached section data
    • Pagination (if applicable)

Why?

• Improves visibility of team productivity
• Enables configurable team management using CSV
• Prevents duplicate API calls
• Ensures scalable and production-ready architecture
• Improves UX with independent section loading
