fix: use type encode methods in payloads instead of raw encoding functions

Replace raw_bytes() with encode() for Address, and append_var_int(self.amount.value)
with append_fixed_bytes(self.amount.encode()) in all payload encode methods.
Also fix ruff errors: missing encoding import in bls/public_key, shadowed builtin
round, inline import in block.py
