SIMULATOR_TYPES and getSimulatorInfo were used directly in the component
body to build the simulator type dropdown. This dragged registry.ts —
which imports every simulator implementation — into the client bundle,
causing a TDZ ReferenceError that broke any route co-loaded with it
(observed as "Error loading route module" on admin events pages).
Fix: pre-build simulatorOptions in the loader and pass them as plain
serializable data. The registry imports remain for the action's
validator but are now only reachable from server-only code.
