Fix spontan doorbell efter HA genstart: restart-safe event_cnt

- input_number initial sat til -1 (sentinel for 'aldrig synkroniseret')
- condition fjernet, event_cnt check flyttet ind i action blok
- counter opdateres ALTID (ogsaa ved wake-up)
- doorbell koerer kun naar old_cnt >= 0 OG new_cnt != old_cnt
- foerste wake-up efter restart synkroniserer stille uden at ringe
