Samir Boulahtit	e61e02fb39	fix(redis): configure maxmemory and eviction policy to prevent OOM ... Redis had no maxmemory set, causing the Prometheus alert expression (used/max) to evaluate to +Inf. Set maxmemory to 100mb with allkeys-lru eviction policy, and guard the alert expression against division by zero. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-01 17:57:38 +01:00
