V3-Enterprise: Remove deprecated environment variables

[rkinginflux]

Brand new install of v3 enterprise via Helm

influxdb3 --version
2026-04-16T23:54:12.184385Z  WARN influxdb3::env_compat: both LOG_FILTER and INFLUXDB3_LOG_FILTER are set; using INFLUXDB3_LOG_FILTER, as LOG_FILTER is deprecated
WARN: Use of deprecated environment variable INFLUXDB3_DATAFUSION_NUM_THREADS: replace with INFLUXDB3_NUM_DATAFUSION_THREADS

Can you update the helm charts in favor of new variables INFLUXDB3_LOG_FILTER & INFLUXDB3_NUM_DATAFUSION_THREADS and remove LOG_FILTER & INFLUXDB3_DATAFUSION_NUM_THREADS ?

In 3.9.x, more env vars were deprecated.

I am not exactly thrilled to replace NFLUXDB3_DATAFUSION_NUM_THREADS with INFLUXDB3_NUM_DATAFUSION_THREADS, because it is not documented - yet, I assume, since it is already in the code.

In influxdb:3.9.1-enterprise (latest version as of now), image metadata includes:

• INFLUXDB_VERSION=3.9.1
• LOG_FILTER=info

LOG_FILTER is baked into the image ENV.
