It reads "Save FAIL" permanently on the Tanmatsu, so on that board the one
indicator meant to make a sick store impossible to miss was instead crying wolf
at every user on every boot. An indicator that is wrong on a whole board is
worse than no indicator: it trains people to ignore it, and it is the first
thing they ask about.
Removed rather than board-gated. Everything it showed, and more, already lives
on Settings > About > Chat store: the backend in use, the segment count and byte
total, when history last saved, and the exact stage plus errno of a failing
save. The chip was a shortcut to a question most people never need to ask.
Also removes the now-unreachable homeStoreChipText() and the per-tick refresh
that ran on every home-screen frame.
Docs updated in the same commit: the user guide had a whole section explaining
how to read the chip, which would otherwise describe something nobody can see.
Replaced with a pointer to the About panel that holds the real answer.
All 8 S3 boards build.
