fix: replace docker-based Redis test with mock, remove Redis-Destructive CI step

Replace testCacheFallback (which stopped/started Docker Redis containers
causing 18-minute hangs) with testCacheFallbackOnFailure that uses a
mock Redis client to simulate cache failure. Tests the same behavior
(reads fallback to DB when cache throws) without Docker manipulation.

Remove the Redis-Destructive CI step and --exclude-group flag since
there are no longer any redis-destructive tests.
