fix(ui): readable error text on dark modal backdrops

Browse Source 
The Material --error reds are muted by design, so error text drawn with the
theme Error() color read low-contrast on the (now deeper) dark modal backdrops —
the audit flagged the seed-migration warning/error lines on dark / dragonx.

Add material::ReadableError(): the theme error lifted toward a legible light red
on dark themes, unchanged on light themes (where it's already a dark red that
reads on a light background). Apply it to the modal error-TEXT sites (lite
first-run, seed backup, seed migration). This is targeted — it never touches the
app-wide Error() used by toasts / badges / status dots — so nothing else shifts.

Verified on the sweep: the "node too old" warning (dark) and "daemon did not
respond" error (dragonx) now read clearly; light themes are unchanged.
