Replace hand-written URL parse/serialize logic in
useDocumentListQueryState with nuqs useQueryStates, reducing boilerplate
and fixing the keyword double-encoding bug. The detail page now reads
search params via useSearchParams() instead of window.location.search,
and interactive elements use semantic <button> with Tailwind icon classes.
- Replace parseParams/updateSearchParams with nuqs createParser parsers
- Stabilise updateQuery callback deps (setQuery only, no query/router)
- Add parseAsKeyword with backward-compat decodeURIComponent for legacy
double-encoded URLs
- Replace RiArrowLeftLine/RiLayoutLeft2Line with Tailwind CSS icon spans
- Use data-testid selectors in detail tests instead of fragile DOM walks
- Rewrite query state tests to use NuqsTestingAdapter
