Logan CusanoandClaude Opus 5.5 40014a47a3 c2-core: Archive "Load more" skipped 150 of every 200 calls
/calls/search scans a 200-row window and returns 50, but the next cursor
was always the last SCANNED row — so with an unfiltered list each page
jumped past the 150 matches it had already read and not shown. Resume
after the last RETURNED row when matches overflow the page; keep the
last-scanned cursor only when the page holds every match (the sparse-
filter case that cursor exists for). Same fix for /calls/eval-queue.

Paged, filterable call archive — the backend for the /calls page.
`GET /calls` returns every call in one unordered shot, which is fine for a
node's handful of active calls and useless as an archive: no order, no
paging, no way to find the orphans. This route is the archive read.
Only the org scope and the started_at ordering go to Firestore, because
that pair is the one composite index that exists (infra/firestore/
firestore.indexes.json). Every other filter runs in Python over a bounded
window, the same shape admin.py's correlation debug route uses — adding a
composite index per filter combination would be a worse trade than reading
10x the page and discarding most of it.
`window_exhausted` says the scan hit its cap before filling the page, so an
empty result means "not in this window", not "none exist".
Open to every org member (viewer included), not just admins: the Firestore
rules already let any member read every call doc in their org
(firestore.rules `calls` → docInMyOrg), so this route exposes nothing a
viewer's browser couldn't already read directly.
