refactor(admin): rebuild the staff sessions page around the operator's question

The page an operator opens to see the day's work did not say who any of it was
for. TreatmentSession::toArray() carries no patient, so the list showed a
service name, a time, and a repeated 40-char button — the same three lines for
every row, with the finished work leading.

The endpoint now sends patient_name and resource_name. They are added in the
controller next to case_uuid/service_name rather than in toArray(), so patient
identity does not leak into every other consumer of that method.

The list is now a queue: unfinished work first, settled work (done, cancelled,
no-show) below it, each group counted. Every row leads with its time, names the
patient, and carries the service, device, session number and area progress on
one meta line. The whole row is the link, so the repeated button is gone.

Also fixes three things the redesign checklist calls out: Latin digits in the
session and area counts (formatNumber), a date repeated on every row of a page
whose title is "today", and a missing error state — a failed request rendered
as "no sessions today", which reads as an empty day rather than a broken one.

Adds the test file the page never had.

+
+| فیلد | توضیح |
+|---|---|
+| `case_uuid` | پروندهٔ درمانِ همین جلسه |
+| `service_name` | نام سرویس |
+| `patient_name` | نام بیمار، از نوبتِ متصل — `null` اگر جلسه نوبت ندارد |
+| `resource_name` | دستگاهِ نوبت — `null` اگر نوبت روی منبع نبوده |

+نباید در هر مصرف‌کنندهٔ دیگرِ آن متد هم بنشیند.
