feat(appointments): resources share the doctors' timeline

Three views become two. The resource lanes were a separate tab, which meant
reading a doctor's free hour on one screen and the laser's on another and
matching them by eye — while in the resource-first model it is the device and
the room that decide whether that hour is really free. They now sit under the
same "زمانبندی" view, below the doctor's slots.

Each lane says how much of its shift is still free, and that number respects
capacity: a minute counts as busy only once the overlapping bookings reach
the resource's capacity, so a three-bed room with two appointments is still
open. Treating it otherwise would silently turn every multi-capacity resource
into a single-capacity one. ResourceFreeTimeCalculator does the sweep and
carries nine cases of its own.

only_bookable=1 keeps resources with no service offering out of the view;
they could only ever render an empty lane. On the seeded clinic that is five
resources down to two.

Two ruler defects the screenshot caught: hours rendered in Latin digits, and
the last label was half-clipped by the container so 21 read as 2.
