Summary

ClickHouse pod in CrashLoopBackOff due to OOM during system.trace_log merge operations
resourcesPreset: small (768Mi) insufficient — merges need ~617MiB
Replace with explicit resources: 512Mi request, 1536Mi limit

Test plan

ArgoCD syncs new values
ClickHouse pod stabilizes (no more CrashLoopBackOff)
Langfuse sessions.filterOptions works again

ClickHouse was OOM-killing during system.trace_log merge operations.
The "small" preset (768Mi) was insufficient — merges need ~617MiB,
leaving no headroom. Replace resourcesPreset with explicit resources
(512Mi request, 1536Mi limit) to prevent CrashLoopBackOff.
