New integration test mirroring a prod bulk import: a dedicated test
library with 30 series whose items share ONE identical created_at
(single-transaction NOW()), the exact data shape that made prod
pagination look broken.
Pins, via the real SSR /series route:
- page 1 renders exactly 24 deterministic series (01-24) with chip
"Page 1 of 2", no Previous, and a Next href carrying library_id and
page (templ escapes & as & inside attributes)
- page 2 renders the remaining 6, disjoint from page 1, chip
"Page 2 of 2", no Next, Previous href correct
- missing page param defaults to page 1; page=0/-3/two clamp to page 1
Guards both the SQL tiebreaker and the /series handler contract;
would fail on any return of the stomp or an unstable sort.
