perf(reports): read every resource's calendar in one batch, and close the owed tests

Writing the query-count test that task 14 owed showed the growth was real: one
resource cost 10 queries, six cost 33 — about five per resource, because the
available-minutes figure walked each resource's calendar on its own.

Holidays, tenant overrides and branch hours are identical for every resource in
a report, so they now load once outside the loop; shifts and exceptions load for
all resources in one query each. The batched path is a new method rather than a
change to rawAvailability, which the booking engine also calls. The test pins
the shape of the growth, not an exact count.

Also landed:

- app:segment:seed-templates with beauty, dental and physio presets. Building
  four segments and their requirements by hand is the first thing a new clinic
  must do and the most tedious; this gives them something to edit instead of an
  empty page. It refuses to touch a service that already has segments unless
  --force, and it will not invent resource types the tenant never defined.
- book-all is all-or-nothing, proven rather than asserted: with a calendar open
  one day a week and a 1-2 day protocol gap, session one finds a slot and
  session two cannot, and every session must come back planned.
- credit_refundable: false takes the credit back with a negative adjustment and
  deletes nothing — the ledger stays append-only.
- the segments editor has frontend tests, including that it sends back what the
  user sees and renders read-only without the permission.

useBranches now returns [] for a non-array payload instead of throwing
"branches.map is not a function" and taking the page down with it.

BookingLocationsScanTest built a Clinic around a Doctor loaded from a different
manager, which Doctrine treats as a new entity; it flushed fine most runs and
failed on cascade in others. It now loads the doctor from the same manager.
