The container always listens on 8080 internally while the user-provided
port is only the host-side mapping. Make this explicit without changing
behavior or the generated config:
- add a named containerAppPort constant and use it in both the docker -p
mapping and the config.toml generation (was a bare 8080 literal in two
places)
- document why config.toml hardcodes the port, so it isn't "fixed" back
to the form value
- relabel the form field to "Porta (host)"
The generated config.toml is byte-identical (port = 8080).
