Production will run Loki 2.9.17 but local-dev uses 3.4.1 (docker-compose.yaml:29). This major version gap between environments may cause behavior differences and make it harder to catch production issues locally. Consider either upgrading production to 3.x or keeping local-dev on 2.9.x to maintain consistency.

OTLP endpoint unavailable after Loki version downgrade
Medium Severity
Downgrading Loki from 3.4.1 to 2.9.17 in local-dev breaks the OpenTelemetry integration. The native OTLP endpoint (/otlp) was introduced in Loki 3.0 and does not exist in 2.9.x. The otel-collector is configured to export logs to http://loki:3100/otlp, which will fail with 404 errors since that endpoint is unavailable in Loki 2.9.17.

Good point. I'm going to revert the downgrade, as it's only temporary; loki 3 should come soon!

Should be done before #1816 and #1815
Note
Low Risk
Simple image tag bump in deployment configs; main risk is Loki version incompatibility/regressions during rollout, with no code-path or data-model changes in this PR.
