Simplify Harbor to standard deployment pattern

- ExternalSecret now pulls only HARBOR_ADMIN_PASSWORD from 1Password
- Removed database, redis, core, jobservice, registry secret references
- Harbor Helm chart auto-generates all internal secrets (standard pattern)
- Reduces complexity and aligns with Harbor best practices

This change removes dependency on 5 1Password fields that should be deleted:
- database-password
- redis-password
- core-secret
- jobservice-secret
- registry-password

Only harbor-admin-password field needed in 1Password item 'the-seas'
