Use trackerless network

[teogeb]

Use the trackerless network, i.e. Streamr 1.0 network instead of Brubeck network.

Future improvements

• use NodeNext module resolution in tsconfig.json when fix(client): Type definition file path network#2377 available
• update to latest TypeScript + eslint (currently incompatible as eslint-config-streamr-ts uses old versions of TypeScript and eslint)
• move some application configs to the config file
