chore!: simplify peer id parsing

[mversic]

• simplify parsing of peer ids (serialize/deserialize it from string now)
  ed01204EE2FCD53E1730AF142D1E23951198678295047F9314B4006B0CB61850B1DB10@irohad2:1339 instead of:
  { "address":"irohad2:1339", "public_key":"ed01204EE2FCD53E1730AF142D1E23951198678295047F9314B4006B0CB61850B1DB10" }
• also move [[sumeragi.trusted_peers]] table into trusted_peers array in the toml config
  this is a required field so it should stand out of config subsections

Migration guide

This change will be reflected in peer_config.toml file.
Minimal configuration before:

chain = "00000000-0000-0000-0000-000000000000"
public_key = "ed01201C61FAF8FE94E253B93114240394F79A607B7FA55F9E5A41EBEC74B88055768B"
private_key = "802620282ED9F3CF92811C3818DBC4AE594ED59DC1A2F78E4241E31924E101D6B1FB83"
