fix(ui): DPI-scale hand-drawn overlays + freeze sweep demo state

Browse Source 
Hand-drawn absolute geometry (dl->AddText offsets, SetNextWindowSize,
explicit ImVec2 button widths, SameLine strides) is immune to the app's
DPI machinery (font-atlas rebuild + ScaleAllSizes), so several overlays
rendered native-size (tiny) on HiDPI / Windows 150% displays. Multiply the
raw logical-px geometry by Layout::dpiScale():

- seed_display: content-aware, DPI-scaled seed-grid column stride (a raw
  130px stride let words collide with the next column's index at 150%)
- lock screen: card/logo/input/unlock-button + all vertical offsets
- migrate-to-seed + seed-backup dialogs: button widths
- send-confirm: confirm/cancel button widths
- about dialog: value-column x, edition inset, link/close button widths
- chat conversation list: row height + padding (fixes the preview clip)

Also freeze demo state during the full UI sweep: guard App::update() on
capture_mode_ so a running daemon's refresh can't clobber the injected
demo state (it blanked Send/Receive/History with a CDB error mid-sweep).

Verified on Windows 4K@150% and locally at font_scale=1.5 (same
dpiScale()==1.5 code path). Adds a DPI-scaling convention note to CLAUDE.md.
