chore: lint & format team modes

What does this MR do and why?

This MR applies Ruff linting and formatting to team modules, user profile modules, and related test/verification scripts to improve code consistency, readability, and maintainability without introducing any functional changes.

Updated files include:

• modes/team_analytics.py
• modes/team_config.py
• modes/team_dashboard.py
• modes/team_styles.py
• modes/team_views.py
• user_profile/profile_ui.py
• user_profile/profile_utils.py
• test_changes.py
• tests/test_batch_logic.py
• verify_batch_users.py
• verify_contribution_fix.py

Changes performed:

• Removed unused imports and redundant code
• Standardized import ordering and formatting
• Applied consistent Ruff formatting across modules
• Ensured lint checks pass successfully

Complexity rule C901 was intentionally ignored, as refactoring logic is outside the scope of this lint/format MR.
