Evan Harris 0305fe1a6f [AI] fix: bound random-sample pre-allocation by available point count ...

`LocalShard::scroll_randomly` pre-allocated its result set with
`HashSet::with_capacity(limit)`, where `limit` is the client-supplied request
limit and is unbounded by default (`StrictModeConfig::max_query_limit` is `None`
unless an operator sets it). A very large limit made the up-front allocation
fail and abort the process (`handle_alloc_error`), which cannot be caught and
returned as an error.

The sample loop inserts at most `min(limit, total points available across
segments)` points, so bound the pre-allocation to what is actually available.
Capacity is unchanged for normal requests; only the pathological case is bounded.

Same class as the search top-k fix (#4321 / #4328) and the in-flight edge fix
(#9374). Adds a regression test.
