P1 Badge Preserve legacy logLevel override during upgrade

Reading VECTOR_LOG only from .Values.logConfig.level causes existing installations that still set logLevel in their override files to silently fall back to info after upgrade, because Helm keeps old keys but this template no longer consumes them. That changes runtime log verbosity unexpectedly in production; this should keep a compatibility fallback to logLevel (or explicitly fail with a migration error) instead of ignoring prior user configuration.
