Update mev-rs and remove patches (#4496)

## Issue Addressed

Fixes occasional compilation errors with mev-rs (see #4456).

## Proposed Changes

- Update `mev-rs` to the latest version, which allows us to remove hacky `[patch]` sections
- Update the `axum` version used in `watch` so LH only uses a single version

beacon_node/execution_layer/src/test_utils/mock_builder.rs
