feat(web): note editing at the reader slider and book banner; Deleted rename

Objective 8a (web half). Reader notes-drawer rows gain an inline editor
(mirroring the bookmark-rename pattern) that PUTs the new content — the
stored position rides along because the server's note PUT hard-sets the
position column (a probe note proved an omitted position NULLs the
anchor). Book-detail banner rows gain Edit/Delete for location notes
and Edit-note/Add-note for the note ATTACHED to a highlight (full-replace
highlight PUT; empty content clears the note; the highlight itself is
never edited from the banner). The edit dialog is centered with the
markdown caption.

The book-detail 'Notes' button becomes 'Deleted' (badge =
deleted-annotation count) and the modal title becomes 'Deleted
annotations' — that modal only ever showed removed annotations.

Verified live in Brave: drawer inline edit round-trips content and
position; banner note edit, highlight-note edit, and delete (tombstone
appears in the Deleted modal); rename renders with the count badge.
