Track paris-barbershop client stack + mailcow-admin playbook in git

Both existed only on the live server / untracked locally until now.
Includes the open/closed status fix: the Filiale status badge was
hardcoded as "Geöffnet · schließt um 20:00" regardless of actual time
(caught showing "open" at 3am) -- now computed against the shop's own
Europe/Berlin clock and real weekly hours.

+# Per-client stack — ONE isolated static-site container per business client.

+# Each client is its own Compose project (name: smb-client-<slug>), so they
+# start / stop / update / remove fully independently and never share state.
+# Booking is handled by the client's own Google Calendar Appointment Schedule
+# (no container), and leads/bookings flow into the shared CRM via the n8n
+# webhooks baked into the client's page — so this stack only serves the site.
+#
+# Don't edit this file per client. Copy the folder with ../new-client.sh, which
+# fills .env (CLIENT_SLUG, CLIENT_DOMAIN) and seeds site/.
