- Fix BookInfo buttons: Left/Right front = scroll down/up, Confirm = no-op,
side buttons retained. Separate Up/Down hints on btn3/btn4.
- Fallback load: try epub.load(true, true) when cache-only load fails,
so Book Info works for unopened books.
- Add "Book Info" to ManageBook menu (BOOK_INFO action) with handlers in
all 4 result sites (Home, Recent, FileBrowser, Reader).
- Fix HomeActivity cover regen: call generateCoverBmp(false) + validate
with isValidThumbnailBmp before falling to placeholder, matching the
reader's multi-tier fallback pipeline. Same for XTC branch.
