Description

GET /v1/streams/{id}/events returns all events with no limit. A high-frequency stream could have hundreds of events making this slow and memory-heavy.

What Needs to Happen

• Add ?limit=50&offset=0 (default 50, max 500)
• Return { data: [...], total: number, hasMore: boolean }
• Add ?eventType=CREATED|TOPPED_UP|WITHDRAWN|CANCELLED|COMPLETED|PAUSED|RESUMED|FEE_COLLECTED filter
• Add ?order=asc|desc (default desc by timestamp)
• Update Swagger docs

Files

• backend/src/controllers/stream.controller.ts (getStreamEvents)

Acceptance Criteria

• Default limit of 50 enforced
• hasMore is accurate
• Event type filter works for all types
