…eGas This commit implements block context overrides for eth_call and eth_estimateGas RPC methods, allowing users to specify block parameters like timestamp, number, difficulty, etc. for call execution context. Key changes: - BlockOverrides added to EthRequest enum variants for eth_call and eth_estimateGas - Block overrides handling implemented in `anvil::eth::backend::mem::state` as `apply_block_overrides()` function (ported from reth) - Add new error type EvmOverrideError to group state and block override related errors (due to fork mode) - State override handling refactored: - Rename `apply_cached_db_state_override()` to `apply_state_overrides()` - Modify to take mutable `CacheDB` reference instead of creating new instance - Consistent pattern for `apply_state_overrides()` and `apply_block_overrides()`
