Event-Driven Frontend Indexing Support

[hman38705]

Descriptions:

Issue #12:

Developer Goal: Standardize events so that external indexers can perfectly reconstruct market states.

Standard Topic Layout:

1. Topic 0: Event Name (e.g., MarketCreated).
2. Topic 1: market_id.
3. Topic 2: Triggering Address.

Verification Checklist:

• Deploy contract and trigger all 5 major events (MarketCreated, BetPlaced, DisputeFiled, ResolutionFinalized, RewardsClaimed).
• Verify using soroban-cli that each event contains the correct market_id as the first data topic.
• git checkout -b features/issue-12-
• Pr Request create your pr against develop branch

Hey, I'd like the opportunity to work on this issue.

I've read through the requirements carefully. The goal is to standardize contract events so external indexers can reliably reconstruct market states. This means ensuring all 5 major events (MarketCreated, BetPlaced, DisputeFiled, ResolutionFinalized, RewardsClaimed) follow the standard topic layout with event name as Topic 0, market_id as Topic 1, and the triggering address as Topic 2.

My plan:
-Review the current event definitions and identify any that don't follow the standard topic layout
-Refactor the event structs to ensure market_id is consistently the first data topic across all 5 events
-Deploy the contract locally and trigger all 5 events
-Verify each event using soroban-cli to confirm the correct topic structure
-Branch off develop using git checkout -b features/issue-12- and submit the PR against develop

I have experience with Soroban event emission and topic structuring so I'm confident I can deliver this cleanly. Can have it ready within a day of being assigned.
Please assign this to me if it's still available!
