Preserve separate Modbus phase timeouts

Connect and write operations each have a one-second limit, and the
response gets two seconds after the write completes. Caller deadlines
remain earlier bounds. Deadline changes are serialized with context
interruption so a read cannot replace the cancellation deadline. A
simulated delayed write verifies the complete response window.
