[REQUEST] Team Lead Approval Dashboard

There is currently no centralized dashboard for Team Leads to review and approve changes to ATT&CK objects or view changes made since a specific ATT&CK release or bundle.

Solution:
Add new Team Lead section to dashboard:

• Admin Settings: Organization settings, default marking definitions, user accounts
• Dashboard: Teams, review, history

Review Page:

• Table of all objects with columns for: multi-select, review status, object type, ID, name, modified, created
• Default sort: most recently modified
• Sortable columns
• Multi-select for approval
• Approve button on row click
• Filter by workflow status
• Object name should link to object page
• Approval restricted to TeamLeadOrHigher

History Page:

• View list of all object changes
• Date picker to filter since specific date
