Build key curve update timelock indexer and pending proposals REST API #1113

Description

@Chucks1093

Summary

Index CurveUpdateProposed and CurveUpdateExecuted contract events and expose REST endpoints for pending and completed bonding curve parameter update proposals per key.

Scope

  • Indexer processes both events into curve_updates table
  • GET /keys/:key_id/curve-updates/pending — returns pending proposals with eta and proposed params
  • GET /keys/:key_id/curve-updates/history — completed and cancelled updates with outcomes
  • ETA countdown computed at request time
  • Cache TTL 60s; invalidated on new curve update event for key

Acceptance Criteria

  • Both events indexed with no gaps
  • Pending endpoint returns accurate proposals with correct eta
  • ETA countdown computed correctly at time of request
  • History returns accurate completed and cancelled records
  • Cache invalidates correctly on new event for affected key

ETA

12 hours
