Add API keys as Docker env vars for n8n community edition 

n8n community edition doesn't have Settings > Variables.

environment variables instead, accessible via $env.* in workflows.

## Setup Requirements
Before activating workflows, configure these environment variables in n8n (**Settings > Variables**):
API keys are passed as **Docker environment variables** in `docker-compose.yml` (n8n community edition doesn't support Settings > Variables). The workflows access them via `$env.VARIABLE_NAME`.
| Variable | Description | Where to find |
|----------|-------------|---------------|
| `TWENTY_API_KEY` | Twenty CRM API key | crm.cosmolocal.world > Settings > API Keys |
| `RESEND_API_KEY` | Resend email API key | `ssh netcup "cat ~/.resend_credentials"` |
| `RESEND_API_KEY` | Resend email API key | Already set (or `ssh netcup "cat ~/.resend_credentials"`) |
To update keys, edit the `environment:` section of the `n8n-cosmolocal` service in `docker-compose.yml` and redeploy.
The Listmonk credentials are hardcoded for internal Docker network access (no external exposure).
