PBS decodes and validates every relay bid and the route re-encodes the winning bid to the beacon node's Accept regardless, so the relay->PBS wire format never changes what the BN receives. Always request SSZ (JSON fallback) instead of mirroring the caller's format: SSZ is smaller on the wire and faster to decode, which matters across N relay bids on the proposal critical path. Mirrors the same change already made to submit_block. Adds a test asserting the relay receives an SSZ-first Accept regardless of the BN's preference (the mock relay now records the Accept it was sent), and updates the now-stale build_outbound_accept doc comment.
