The physics engine runs continuously, so pausing charts was misleading -
users might think the simulation stopped when it didn't. Charts now
always update automatically.
Also fix Streamlit deprecation warnings by replacing use_container_width
with width parameter (will be removed after 2025-12-31).

InstrumentServer is a general-purpose SCPI-over-TCP server that can
host any device implementing the SCPIDevice protocol (process method).
Moving it from simulation/ to instruments/transport/ reflects this:
- simulation package now depends on instruments package
- InstrumentServer can host both virtual and real instrument adapters
- Added SCPIDevice Protocol for type-safe device registration
Create SimulationServer that wires physics engine to all virtual
instruments and exposes them over TCP. Add 'serve' CLI command to
start the server with configurable ports and physics rate.
