Add deterministic event ordering test for emit sequence in resolve_market

[greatest0fallt1me]

Description

resolve_market in lib.rs emits multiple events (MarketResolvedEvent, OracleResultEvent, FeeCollectedEvent). Off-chain indexers depend on order. Add a test that captures env.events().all() and asserts the expected sequence.

Requirements and Context

• Use env.events() introspection
• Assert ordering and topic shapes
• Document the ordering contract in lib.rs rustdoc
• Must be secure, tested, and documented
• Should be efficient and easy to review

Suggested Execution

1. Fork the repo and create a branch

   git checkout -b test/resolve-market-event-ordering

2. Implement changes
   • contracts/predictify-hybrid/tests/resolve_market_event_order.rs (new)
   • contracts/predictify-hybrid/src/lib.rs (only doc comments)
3. Test and commit
   • cargo test -p predictify-hybrid resolve_market_event_order -- --nocapture
   • Cover edge cases: tie outcome, single-winner outcome
   • Include test output and notes in the PR

Example commit message

test: lock event emission order in resolve_market

Acceptance Criteria

• Ordering documented in lib.rs
• Test asserts exact sequence
• Includes a regression note in test header
• No unwrap() introduced

Guidelines

• Avoid using exact ledger timestamps in assertions
• Minimum 95% coverage of touched files
• Clear documentation and inline comments
• Timeframe: 96 hours

Hi maintainers, I would like to apply for this issue if it is available.

If assigned, I will keep the change scoped to the resolve_market event ordering contract: add deterministic tests around env.events().all(), cover the tie and single-winner paths, assert the expected event sequence/topic shapes, and add concise rustdoc documenting the ordering expectation without changing contract behavior.

I will wait for maintainer/GrantFox assignment before cloning, implementing, or opening a PR.
