Add bulk selection and actions to admin user table

[Copilot]

Admin panel lacked ability to perform actions on multiple users simultaneously, requiring one-by-one operations for delete/approve/reject.

Changes

Frontend

• Individual and select-all checkboxes with indeterminate state support
• Bulk actions bar showing selection count and action dropdown (Approve/Reject/Delete)
• Row highlighting for selected items

Backend

• Three new endpoints: POST /api/user/bulk/{delete,approve,reject}
• Batch RCON commands for whitelist sync (Java/Bedrock editions)
• User existence validation before operations

API Contracts

// Request body for all bulk operations
{ userIds: number[] }

// Response
{ message: string, count: number }

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• checkpoint.prisma.io
  • Triggering command: /usr/local/bin/node /usr/local/bin/node /home/REDACTED/work/convitelist/convitelist/backend/node_modules/prisma/build/child {"product":"prisma","version":"5.22.0","cli_install_type":"local","information":"","local_timestamp":"2026-01-23T13:13:20Z","project_hash":"fb64e43d","cli_path":"/home/REDACTED/work/convitelist/convitelist/backend/node_modules/prisma/build/index.js","cli_pa (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
