chore(l1): review p2p logs

[fedacking]

Motivation

Currently the P2P logs are verbose, and don't use the structured format we want for logs in some cases. As such, we aim in this PR to review and change the format of the logs.

Description

• Removed Macros for peer logging, changed to be inline.
• Modified Node Display format to include the client name.
• Lowered "Broken pipe with peer, disconnected" from error to debug
• Added comments explaining why we might want debug logs.

Example of output in this PR:
2025-10-24T17:59:52.294734Z DEBUG ethrex_p2p::rlpx::connection::server: connection failure peer=Nethermind:0xb7b2…10fb(70.105.250.99:30303) error_text=Failed to initialize RLPx connection error=Peer disconnected due to: Too Many Peers
