feat(annotations + player): bookmark rows in the banner, stacked volume panel, badge parity for comics/manga

Annotations banner: audio/text bookmarks join notes and highlights —
third row kind (bookmark glyph indicator, H:MM:SS / Page N / Chapter N
friendly labels), edit-note/delete actions branch by kind, and the
banner's export now covers all annotations. The archived ledger
(ListDeletedAnnotationsForBook) already tombstoned bookmarks equally
and Restore/Purge take annotation_type=bookmark — verified live:
delete → restore brings the row back with its note intact.

Volume: the dragger sits BELOW the mute icon in the panel (stacked
flyout shape) with the horizontal slider from the last round.

Badges: the real fix for comics/manga — format_group only knows
'comic_archive' (manga_type is unreliable across sources), so the
comic/manga split is resolved from the LIBRARY type server-side.
handlers.MediaBadgeKind + BookInfo.Badge at every construction site
(dashboard SSR + sections API, collections, series, and the bookshelf
search grid — which was also missing FormatGroup entirely, so no card
ever badged there). Both renderers (templ + dashboard.ts) switch on
the resolved badge. Verified: All-Books grid renders 2 Comic + 3
Manga badges, dashboard the audiobook one.

Infra: header.templ main.js src gains ?v=<stamp> — browsers keyed an
intermediate bundle by URL and served it across rebuilds (the stale
'Add note' the user saw); bump the stamp when JS stale-shadows.
