feat(debyltech-cloud): lock customers to read-only, no discovery

Customers are admin-created accounts in per-customer groups. They should
read what staff share with them and nothing else. Checked against a test
customer in the UI, and by running the sharee and contacts-menu search
services as that user.

- shareapi_exclude_groups=allow, list [admin]: only staff can share. Exclude
  mode ("yes") only disables sharing for users whose groups are ALL
  excluded, so it never catches a customer in their own group.
- User/group autocomplete off. By default a customer typing "bas" found the
  owner's account. Staff share by exact group name; LibreSign signers are
  found by email.
- New shares default to View only (shareapi_default_permissions=1).
- files default_quota 0 B, so customers get no personal storage. Staff in
  cloud_debyltech_staff_users are exempted (skipped if not yet created).
- No "Leon Green" sample contact in new address books.
- The verify script fails the deploy if any isolation setting drifts.
- README: staff and customer onboarding checklist.
