Configure Traefik proxy and HTTPS. See #7768 for reference

### Build the docker-compose file

Setting up Traefik as reverse proxy requires setting the following labels:

        labels:
          - traefik.enable=true
          - traefik.http.routers.trilium.entrypoints=https
          - traefik.http.routers.trilium.rule=Host(`trilium.mydomain.tld`)
          - traefik.http.routers.trilium.tls=true
          - traefik.http.routers.trilium.service=trilium
          - traefik.http.services.trilium.loadbalancer.server.port=8080
          # scheme must be HTTP instead of the usual HTTPS because Trilium listens on HTTP internally
          - traefik.http.services.trilium.loadbalancer.server.scheme=http
          - traefik.docker.network=proxy
          # forward HTTP to HTTPS
          - traefik.http.routers.trilium.middlewares=trilium-headers@docker
          - traefik.http.middlewares.trilium-headers.headers.customrequestheaders.X-Forwarded-Proto=https

### Setup needed environment variables

After setting up a reverse proxy, make sure to configure the [missing note].

### Example `docker-compose.yaml`

    services:
      trilium:
        image: triliumnext/trilium
        container_name: trilium
        networks:
          - traefik-proxy
        environment:
          - TRILIUM_NETWORK_TRUSTEDREVERSEPROXY=my-traefik-host-ip # e.g., 172.18.0.0/16
        volumes:
          - /path/to/data:/home/node/trilium-data
          - /etc/timezone:/etc/timezone:ro
          - /etc/localtime:/etc/localtime:ro
        labels:
          - traefik.enable=true
          - traefik.http.routers.trilium.entrypoints=https
          - traefik.http.routers.trilium.rule=Host(`trilium.mydomain.tld`)
          - traefik.http.routers.trilium.tls=true
          - traefik.http.routers.trilium.service=trilium
          - traefik.http.services.trilium.loadbalancer.server.port=8080
          # scheme must be HTTP instead of the usual HTTPS because of how trilium works
          - traefik.http.services.trilium.loadbalancer.server.scheme=http
          - traefik.docker.network=traefik-proxy
          # Tell Trilium the original request was HTTPS
          - traefik.http.routers.trilium.middlewares=trilium-headers@docker
          - traefik.http.middlewares.trilium-headers.headers.customrequestheaders.X-Forwarded-Proto=https

    networks:
      traefik-proxy:
        external: true
