ClickHouse was OOMing during MergeTree merge operations on system log
tables (trace_log grew to 6.3GB/302M rows). This caused cascading
failures: CH crashes → langfuse-web migration fails → crash loop
(82 restarts in 8 days).

Bump CH memory: requests 1Gi→2Gi, limits 3Gi→5Gi. Also truncated
accumulated system log tables (~8GB freed) as immediate relief.
