Describe your changes and provide context

Improves the giga test suite to check recepits, and adds a check for EIP-1559 txs.

Testing performed to validate your change

Adds test cases, all pass.

Note

Low Risk
Test-only changes that tighten parity assertions; risk is mainly increased flakiness if receipt fields legitimately diverge across executors.

Overview
Adds cross-mode receipt parity checks to giga_test.go by routing GetTransientReceipt through the correct keeper (V2 vs Giga) and asserting equality across consensus-relevant receipt fields (status, gas used, logs bloom/topics, contract address, and EffectiveGasPrice).

Updates existing Geth↔Giga and sequential↔OCC comparisons to call CompareReceipts, adjusts transfer fixtures so tipCap << feeCap to expose EIP-1559 effective price differences, and introduces TestGigaVsGeth_EffectiveGasPrice_DynamicFee as a regression test for min(feeCap, tip+baseFee) behavior. Also updates the balance-transfer test to compute gas cost from receipt.EffectiveGasPrice instead of a hard-coded gas price.

isGigaMode includes mode unsupported by constructor

Low Severity

isGigaMode() includes ModeGigaWithRegularStore, but NewGigaTestContext — the sole constructor for GigaTestContext — does not treat that mode as giga-enabled (line 77: gigaEnabled only checks ModeGigaSequential and ModeGigaOCC). A context created with ModeGigaWithRegularStore would get a non-giga app via NewTestWrapperWithSc, yet GetTransientReceipt would route to GigaEvmKeeper on that uninitialized app. The sibling constructor NewStateTestContext handles this mode correctly via NewGigaTestWrapperWithRegularStore.
