Two wallets-modal changes:
- The wallet list now always renders at its max height (kMaxVisibleRows) instead
of shrinking to the wallet count, so the modal is a consistent size whether you
have one wallet or many — fewer rows leave empty space, more than 7 scroll.
- Add a "Scanned folders" manager: each user-added scan folder is listed with a
control to stop scanning it (removeExtraFolder + save + re-scan so its wallets
drop out). Paths front-elide to keep the identifying leaf visible, with a
full-path tooltip. The card-height math reserves the manager's rows so nothing
clips. Two new i18n keys (wallets_scanned_folders / wallets_remove_folder),
translated across all 8 languages; CJK subset rebuilt.
Verified on the sweep at 1.0 and 1.5x DPI: max-height list on both the few- and
many-wallet surfaces, the folder manager renders and stays clear of the footer.
