feat: Forza modalità parallela con default 2 inverter

- Rimosso timeout e detection automatica
- Sempre modalità parallela forzata
- Default 2 inverter se parallel discovery fallisce
- Registra discovery per voltronic_inv1 e voltronic_inv2

NOTA: Se gli inverter non rispondono a QPGS, NON sono in modalità parallela.
Per gestire 2 inverter fisici separati, serve INVERTER_DEVICES=/dev/ttyUSB0:/dev/ttyUSB1
