The desktop /profile/history page and the mobile Library "History" tab
each hand-rendered reading history with separate markup, which had drifted:
the Library tab was a read-only 2-column list with no date and no
removed-chapter / whole-manga fallbacks, while /profile/history was a
3-column list with a per-row clear button. Extract a shared HistoryList
component so the two can't diverge again.
- New HistoryList.svelte owns row rendering, the optimistic-removal UX
(instant remove, rollback + inline error on failure), and the empty
state. Clear is opt-in via an `onClear` prop so a caller can render
read-only, but both surfaces now pass it.
- The mobile Library History tab gains the clear action, the "Read {date}"
line, and the (chapter removed) / whole-manga fallbacks it was missing.
- Continue label is built in script (was inline) so the " — page N" suffix
keeps its spaces — Svelte trimmed them at the {#if} edge, rendering
"Chapter 3— page 7". Both surfaces now read "Continue Chapter N".
Net -204 lines across the two pages. Uploads parity on the mobile tab is
left as a follow-up (it needs the library loader to fetch uploads).
