[Backend] — Extend `CreatorEvent` entity with campaign duration, prize pool, reward distribution, entry fee & branding

[Olowodarey]

Background

`src/matches/entities/creator-event.entity.

Goal

Add columns to CreatorEvent for the new campaign fields, write a migration,
and update the indexer's EventCreated handling to capture them from the
(updated) contract event payload.

Tasks

1. Entity changes (src/matches/entities/creator-event.entity.ts):
2. Migration: new file in src/migrations/, e.g.
3. Indexer — extractEventData() 'EventCreated' case: add
4. Indexer — handleEventCreated(): pass the new fields through to
   • start_time: new Date(Number(data.start_time) * 1000)
   • end_time: new Date(Number(data.end_time) * 1000)
   • prize_pool: this.readStr(data, 'prize_pool') || '0'
   • reward_distribution: (data.reward_distribution as number[]) ?? []

Acceptance Criteria

• creator_events table has the 8 new columns + 2 new indexes after
• EventCreated events that include the new fields populate all 8
• EventCreated events that are missing the new fields (e.g. emitted by
• Existing rows (pre-migration) get sensible backfilled

Hi maintainers, I’d like to work on this.

Plan: update both CreatorEvent entity surfaces if needed, add the migration for the 8 campaign fields and 2 indexes, wire the new EventCreated payload fields through the indexer, and cover new/old event payloads plus backfilled existing rows.
