Few things here:
1. Merge automatic and manual backup to a single page
2. State that ADMIN_PASSWD must be enabled for backup or restore to work
3. Remove unneeded usage of --admin-passwd from commands
inside the container
4. Make the main backups page (not clickable through the interface,
available only in search) redirect to information about backups
instead of displaying text
5. Add HTTPS port to canonical docker-compose.yml
6. Clarify build option in the canonical docker-compose.yaml
