d590eda22a fix(libraries): exclude manga chapters from admin Unmatched queue (#275)
* fix(libraries): exclude manga chapters from admin Unmatched queue

Manga chapter rows are internal sub-units resolved through their series
and intentionally stay 'pending' with type='ebook', so they flooded the
admin Unmatched Items view even after the series matched successfully.
Apply the shared MangaChapterExclusionWhere guard to both the count and
list queries, matching every other catalog listing surface.

Fixes #204

* test(libraries): scope unmatched-queue regression test with a unique per-run tag

The regression test seeded fixed literal titles and asserted an exact
total for q=Unmatched+Test, which is collision-prone against a shared
SILO_TEST_DATABASE_URL database: leftover or concurrently seeded rows
matching the literal query would skew the count and flake the test.

Embed a unique per-run tag (issue204-<unixnano>) in every seeded title
and scope the search query to that tag (URL-encoded), so the exact
total assertion only ever sees this run's rows. Assertions are
otherwise unchanged: the manga chapter stays excluded, the plain
pending ebook stays present, and total == 1.
