Log stream fixes

[loneil]

Loki logging can be optionally enabled, see details here

Some things to sort out for local docker compose start up and Helm deployments.

1. Promtail container startup error, local

After running docker compose -f docker-compose.logs.yml -f docker-compose.yml up
scripts-promtail-1 fails to start with:

2025-01-20 15:40:13 level=error ts=2025-01-20T23:40:13.765806511Z caller=main.go:170 
msg="error creating promtail" error="failed to make journal target manager: creating journal reader: failed to open journal in directory \"/var/log/journal\":
no such file or directory"

2. Helm chart setup for infrastructure

Need to set up necessary Loki streaming infra and config in a way that it can deploy and update to our environments.
Ideally would be stood up for pull request environments as well but might not be worth it if complicated.

3. Parameterize log filter
In log-stream.ts it references:

const handleLokiWebSocket = (tenantId: string, ws: WebSocket) => {
  const loki = new WebSocket(
    `${LOKI_URL}/loki/api/v1/tail?query={container_name="scripts-traction-agent-1"} |= \`${tenantId}\``
  );
...

Think that hard coded container name is specific to local docker standup.

4. Error handling
If anything goes wrong starting the log stream there's no feedback to the frontend, or anything logged in the Node app.
