fix(ui): prevent text/button cutoff and scale hand-drawn geometry at HiDPI

Findings from a UI-cutoff audit — each is a spot where an in-tree helper
(truncateMiddle / TruncateToWidth / measured button width / the *dpiScale/*hs
factors) was bypassed:

- notifications: the toast-pill height/padding/icon-gap were raw logical px while
  the icon/text drawn inside are DPI-baked, so they clipped the pill at HiDPI.
  Scale the geometry by dpiScale (not the already-scaled glyph metrics).
- settings: in the two-column NODE & SECURITY layout the data-directory path could
  overrun into the Daemon-binary column (shared draw list, no clip rect between
  them). Middle-ellipsize it to the column width; the full path stays in the
  tooltip + click-to-open + copy.
- send: the "Confirm & Send" button width came straight from the schema and was
  never measured against the label, clipping the Russian translation on the
  pre-broadcast dialog. Size to max(schema width, measured label + padding).
- balance: the recent-tx address-column offset missed the `* hs` DPI factor its
  sibling (amount-right-margin) uses, overlapping the type label at HiDPI.
