fix(qdrant): disable anonymous telemetry by default (#747)

Qdrant's upstream default enables anonymous telemetry to telemetry.qdrant.io,
which doesn't match NOMAD's offline-first "zero telemetry" posture. Adding
QDRANT__TELEMETRY_DISABLED=true to the container environment turns it off for
fresh installs and reinstalls.

Existing installs keep their current telemetry-enabled container until the
Qdrant service is force-reinstalled via the Knowledge Base panel or the next
container recreation — Docker bakes Env into containers at create time, so
env changes require a new container.

Closes #742
