Review Comment:
IGNITE-28216 fixes the known root cause: specific missed lastApplied() bumps
in partition processing. This PR adds a detection mechanism: if truncation
below applied index ever happens (from this bug or any future bug), we fail the
node instead of silently corrupting data.
As a result these are complementary. IGNITE-28216 prevents the gap; our PR
catches it if it ever occurs anyway, due to some other unknown bug or nuance --
a similar future bug would again cause silent corruption with no indication of
something went wrong.
