SCP-5012 Upgrade `marlowe-apps` to use `marlowe-sync`

tracing the un-hashed bytes of the script integrity

1. Aligned `marlowe-apps` environment variables to those used for
   the local docker environment.
2. Move Runtime-related command-line options to
   `marlowe-runtime:config`.
3. Kept Chainseek-related command-line options in `marlowe-apps`,
   but we really need a `marlowe-chain-sync:config` package.
4. Updated documentation to match environment variables and
   default hosts/ports.
5. Deferred `exe:marlowe-pipe` to a subsequent PR.
