feat: enable CORS for local reth (#2665)

## What ❔
This PR adds the `--http.corsdomain "*"` option to Docker Compose files
to enable CORS (Cross-Origin Resource Sharing) on locally running Reth
nodes.

## Why ❔
Enables web applications like dapp-portal and block-explorer to make
requests to the local RPC endpoint. Without CORS enabled, browser
policies block these requests, causing the applications to fail.
