test(reset): run dice and re-entry coverage from firmware 7.14.3

The bitcoin-only 7.14.3 release line carries the dice-entropy backport, and
no firmware between 7.14.3 and 7.15.0 exists without it, so the 7.15.0 gates
were exact only for the 7.15 line: against 7.14.3 the dice end-to-end test,
the ceremony re-entry regression (the host-chosen-seed guard), and report
Section K all skipped silently, and CI went green with zero device-level
dice coverage.

Gates move to 7.14.3, which is exact for the whole fleet. Section K retitled
accordingly.
