Add 6 integration test cases for Pyth Stylus Receiver contract

- test_get_price_after_multiple_updates: Tests price retrieval after multiple updates
- test_get_price_unavailable_no_update: Tests PriceUnavailable error for unupdated price
- test_get_price_no_older_than_unavailable_random_id: Tests PriceUnavailable error for random ID
- test_get_price_no_older_than_valid_max_age: Tests successful price retrieval with max age
- test_get_price_no_older_than_too_old: Tests price retrieval with age constraints
- test_multiple_updates_both_ids: Tests multiple price updates with verification of both IDs

Also added PartialEq derive to PythReceiverError enum to enable test assertions.
All tests pass successfully with cargo test.
