Meta: Document Remaining RPC Hive Failures

[MysticRyuujin]

I have broken down the current Hive rpc-compat test failures into a few categories that need fixing:

• Accepting non 0x prefixed strings
• eth_estimateGas EIP-7702
• Still returning totalDifficulty
• eth_simulateV1 issues (of which there are many)

Example Failures:

• debug_getRawBlock/get-invalid-number
• eth_estimateGas/estimate-with-eip7702
• eth_getBlockByHash/get-block-by-hash

• fix: eth_simulateV1 future blocks and validation error +6
• omit totalDifficulty from BlockResult post-merge +7
• add blockTimestamp to transaction RPC results +9
• fix: map GAS_PRICE_BELOW_CURRENT_BASE_FEE to correct error code in eth_simulateV1 +1
• fix sub-frame revert bug in ethTransferLogs +1
