Add profile_config_term for external program integration
Expose a bundled cmdliner term that allows other programs (like sortal)
to easily use Immich profiles set up via the CLI. The Profile_config
module bundles logging, HTTP config, and profile selection into a single
term that can be combined with with_client for authenticated API access.
