Subject: [PATCH] fix(evolution): prevent Evolution instances from getting
 stuck in 'close' state

Evolution is a webhook-based integration that should always be considered
'open' since it passively receives events. Three changes fix the issue:

1. monitor.service.ts: Always call connectToWhatsapp() for Evolution
   instances on server restart, regardless of stored connection status.
2. instance.controller.ts: Call connectToWhatsapp() for Evolution
   instances during creation to initialize Chatwoot settings.
3. evolution.channel.service.ts: Restore stateConnection to 'open' and
   persist it to DB when connectToWhatsapp() is called in init mode.

Closes #2419
