[APP][Pro] SolarEdge + Growatt TCP modbus

Rather than making exportlimitenabled/exportlimitpowerrate globally setable (which risks issues on TLS and other variants without a compatible Modbus meter), I added an ‘ems_control’ checkbox to the regular Growatt driver settings. Only when the user explicitly enables this will the capabilities become writable and the registerCapabilityListener

Ah, yeah, that’s the same I did for the Growatt TLS, must have overlooked that.
