- Add EventMetrics struct with tickets_sold field (zero-initialized) - Add StorageKey::Event(BytesN<32>) and StorageKey::EventMetrics(BytesN<32>) - Update EventDetails: id changed to BytesN<32>, added token field - Implement create_event to persist EventDetails and EventMetrics in storage - Add state logic test verifying all fields saved correctly in env.storage()
- Replace weak auth-only test with a real integration test that uploads the contract's own compiled WASM via contractimport!, calls upgrade_contract, and verifies the contract remains functional after the upgrade (storage preserved) - Add test_upgrade_contract_not_initialized_fails test - Update CI workflow: install wasm32v1-none target and build WASM before running tests (contractimport! requires the file at compile time)

Closes #221
The upgrade_contract function already existed and was correctly calling env.deployer().update_current_contract_wasm(new_wasm_hash). The task was really about proving it works with a proper integration test.
The old test was weak — it just passed a zeroed-out hash, expected it to fail, and called that "success". I replaced it with a real integration test that:
Builds the contract's own WASM using contractimport!
Uploads it to get a valid on-ledger hash
Calls upgrade_contract and asserts it succeeds
Verifies the contract is still callable after the upgrade (storage intact)
I also updated the CI workflow to install the wasm32v1-none target and build the WASM before running tests, since contractimport! needs the file present at compile time.
