feat(platform): add member count and created date to teams table

[Israeltheminer]

Summary

• Extend getMyTeams and listOrgTeams Convex queries to return memberCount and createdAt for each team
• Add member count and relative created date columns to the teams settings table
• Add TeamMembersPreloader component to eagerly subscribe to team member data, so detail/edit/delete dialogs open instantly
• Wrap teams table in PageSection for consistent settings page layout
• Update all test fixtures and mocks to include the new fields

Test plan

• Verify teams table shows member count and relative created date columns
• Open team detail/edit/delete dialogs and confirm data loads instantly (no spinner)
• Run convex/members/__tests__/queries.test.ts — all tests pass
• Run teams table component tests — all pass
• Verify layout matches other settings page sections

Summary by CodeRabbit

• New Features
  • Teams table now displays member count for each team

📝 Walkthrough

Walkthrough

This PR extends team data returned by backend queries to include memberCount and createdAt fields. The Convex queries getMyTeams and listOrgTeams are modified to compute member counts via parallel teamMember lookups and include creation timestamps in results. The frontend teams table is updated to display these new fields as additional columns and to eagerly preload team member data. Test fixtures are updated throughout to populate the new fields, and a mock for team member queries is added to test dependencies.
