fix(webhooks): Use numeric method value (1=POST) in notification payload

The webhook notification payload was using string 'POST' for the method
field, but Sonarr/Radarr API expects numeric values:
- 1 = POST
- 2 = PUT

Also added onManualInteractionRequired: false to match the schema.

Fixes: Radarr/Sonarr rejecting webhook configuration with validation errors
