feat(admin): build the last two screens, and pin spacing with a test

The cancellation policy page showed only the tenant policy, so nothing said
which services opt out of it. Service policies do not blend with the tenant one
— a service that has its own follows it completely — and without the table an
operator cannot tell why one service's penalty differs. It lists them with a
link to each service.

The waitlist had the matches endpoint and no way to reach it. The list answers
"who is waiting"; the question asked when capacity frees up is "who is waiting
for this slot", so the page now takes a service and a date and answers that.
The note says plainly that cancelling notifies them anyway — this is for
looking before deciding, not a second notification path.

Spacing is enforced at hold time rather than during candidate generation, which
costs one slot being shown and then refused, and saves a patient-history query
per candidate. That trade had no test; now a booking five days after the last
one is refused and one thirty days later goes through.

Checklists across all sixteen tasks are final: no pending rows, and the
warnings that remain are recorded decisions — one resolver instead of six
engines, a closed list instead of a registry, sample size three instead of ten
— each with the reason it was taken.
