clear() forces a full physical screen repaint on the next refresh();
erase() just blanks the buffer content and lets curses diff against
what's already on the terminal, sending only the changed cells. The
main cert list and the cert-entry form both redraw on every keystroke,
so clear() there meant retransmitting the whole screen on every arrow
key / typed character — slow and flickery over a low-bandwidth link
like a serial console.
One-shot dialogs (show_confirm, _msg, _error) draw once and don't
loop-redraw, so they keep clear() as-is — no benefit to changing them
and it's one less thing to get wrong.
Also handle curses.KEY_RESIZE explicitly in the main list loop: force
one real clear() right after a detected resize, since erase()'s diff
against the pre-resize screen model isn't reliable across a genuine
dimension change. Screen-size changes were already picked up on the
next redraw before this (draw() runs unconditionally every loop
iteration), this just guarantees a clean repaint at the moment of the
actual resize instead of trusting the diff engine through it.

CertInfo.email was already populated from index.txt but never
rendered; add it as a fixed-width column next to CN in the cert
list rows (blank when unknown).

init_colors() now survives a terminal rejecting every init_pair() call
(some serial-console terminfo entries claim start_color()/COLORS support
but can't actually set custom pairs), but that exposed a follow-on bug:
the list cursor and the cert-form Continue/Cancel buttons indicated
selection purely via the COLOR_SELECTED color pair, so once that pair
silently no-ops the current row/button becomes indistinguishable from
an unselected one. Add curses.A_REVERSE alongside the color pair for
the selected state — a plain video attribute that doesn't depend on
custom-pair support, so the cursor stays visible either way.
