The boot crash-report prompt + the About-page export button are only useful
where the saved coredump file can actually be retrieved and sent to the devs:
the T-Deck (SD card) and Tanmatsu (FFat, via the launcher file manager). On the
Heltec V4 there's no SD and no user-reachable internal storage, so the prompt
was a dead end. Gate crashDumpCheck() to those boards only — on the V4 the dump
is never detected, so the whole crash-report UI stays off (everything downstream
gates on s_crash_dump_size). The panic coredump still sits in its flash
partition for a USB/esptool pull if ever needed.
