node-split: add smeshing identities endpoint to smesher service PoC

[kacpersaw]

Description

Created smeshing identities endpoint based on #6266
Added states for post, poet and atxes.

TODO after PoC: state switch validation, better error handling

enum IdentityState {
  UNSPECIFIED = 0;

  WAIT_FOR_ATX_SYNCED = 1;
  RETRYING = 2;

  WAITING_FOR_POET_REGISTRATION_WINDOW = 3;
  POET_CHALLENGE_READY = 4;
  POET_REGISTERED = 5;
  WAIT_FOR_POET_ROUND_END = 6;
  POET_PROOF_RECEIVED = 7;

  GENERATING_POST_PROOF = 8;
  POST_PROOF_READY = 9;

  ATX_READY = 10;
  ATX_BROADCASTED = 11;
}
