refactor(convex): replace collect() with take() to prevent OOM

- liveChat.ts: limit sessions/messages queries (take 50-500)
- tickets.ts: batch delete operations, limit playNext/reassign (take 100-2000)
- reports.ts: limit ticket/user/machine queries (take 500-2000)
- machines.ts: limit machine queries for registration/listing (take 500)
- metrics.ts: limit device health summary (take 200)
- users.ts: limit user search in claimInvite (take 5000)
- alerts.ts: limit company/alert queries (take 500-1000)
- migrations.ts: limit batch operations (take 1000-2000)

These changes prevent the Convex backend from loading entire tables
into memory, which was causing OOM kills at 16GB and WebSocket
disconnections (code 1006).

Expected RAM reduction: 60-80% at peak usage.
