Resources never needed a branch: devices and rooms belong to the clinic
itself, and the picker always had exactly one option — a mandatory click
that decided nothing.
- `address_uuid` is now optional on resource and pool creation; when it is
missing the environment's own address is used. Clients still sending it
keep working.
- The panel no longer asks for or displays a branch anywhere: resource
form, list column and filter, pool form and column, detail row, and the
resource-first booking page.
- Availability no longer gates on `doctor_addresses.active`. That gate shut
down every device of a clinic whose address row happened to be inactive,
with a message no page in the panel could act on — no endpoint writes
that column at all.
`address_id` stays on the resource: the timezone and the tenant pair are
derived from it. It is simply no longer the user's decision.
