feat: remove Gotify notification service

Removed Gotify completely from infrastructure, replaced by Mattermost:

- Removed gotify/compose.yaml stack
- Removed Gotify environment variables from arty.yml
- Removed Gotify from compose.yaml include list
- Removed Gotify volume backup from Restic configuration

Gotify has been fully replaced by Mattermost for:
- Infrastructure notifications (Netdata, Watchtower, Restic)
- n8n workflow notifications
- Team collaboration and chat
