chore(logging): remove redis-progress-markers feature flag (#5287)

* chore(logging): remove redis-progress-markers feature flag

Promote the Redis progress-marker write path to permanent behavior now that
the flag is fully rolled out. Block markers always write to Redis (primary),
keeping the durable jsonb_set UPDATE fallback when Redis is unavailable.

Removes the flag registry entry, its REDIS_PROGRESS_MARKERS env fallback, and
the per-session flag resolution in the logging session.

* chore(logging): drop vestigial readProgressMarkers plumbing

Follow-up to the redis-progress-markers flag removal. With the flag gone the
completion fold always reads Redis markers, so the readProgressMarkers param
(and its dead false branch) is removed end-to-end:

- drop the param from completeWorkflowExecution and CompleteWorkflowExecutionParams
- read progress markers unconditionally in the completion fold
- delete the orphaned isFeatureEnabled mock and the flag-off / flag-throws
  marker tests (states the code can no longer produce)
