test(knowledge): give the member-tombstone budget test its own timeout

`finishes a pass within its page budget` times out against the shared 30s
default on a loaded CI runner. It is a load flake, not a regression: the same
commit went green on the `push` integration job and timed out on `migrate`,
and it runs in ~4s locally.

The cost is real work, not a hang. The test seeds
`MEMBER_TOMBSTONE_RECONCILE_PAGES_PER_RUN * 500 + 500` documents specifically
so one pass cannot finish inside a single run's budget, then observes and
re-lists all of it. That volume is the assertion, so trimming it to fit the
default would stop proving the multi-run path. Given its own 120s budget
instead, matching the per-test timeouts already used elsewhere in this
directory, with a comment recording why.

Unrelated to this branch's fork-sync work - the file is byte-identical to
staging and arrived with the merge - but it was failing this PR's CI, and a
flake left alone becomes one everybody learns to ignore.
