This looks wrong to me. The right thing to set .name to here is NullOptional, not empty string.

Changes:
CharSpan::fromCharStringinstead ofCharSpan("foo")because the latter is off-by-one-1for sizes in a few unit tests because they also used sizeof instead of strlenEnabled check on write, but not on read (since I imagine controllers have to be lenient).
However chip-tool enables this on read too, so that certification/validation catches invalid devices.
