fix(tui): resolve daemon URL from config

The TUI arm of the umbrella binary hardcoded http://127.0.0.1:7070 instead
of going through MaestroConfigFile::resolve_daemon_url, which every CLI
subcommand uses. On a host whose [daemon].bind_addr is not the default port,
`maestro list` worked and `maestro tui` could not connect.

RunConfig.daemon_url is now the override rather than the final URL; the TUI
resolves it against the config file it already loads for its UI settings.
