[refactor](trx-client): use RigState constructors

Replace duplicated RigState initialization with new constructor methods.

Changes:
- Use RigState::new_uninitialized() in main.rs
- Use RigState::from_snapshot() in remote_client.rs
- Remove standalone state_from_snapshot() function

These constructors eliminate 155 lines of duplicated struct literals
and provide clear semantics for different initialization contexts.
