feat(auth): add bot name lookup and suggestion support in bot responses

Implemented a new `bot_from_name` method in `AuthService` to retrieve a bot's UUID by its name, enabling explicit bot selection via a `bot_name` query parameter in the authentication endpoint. Updated `auth_handler` to prioritize this parameter, fall back to the first active bot when necessary, and handle cases where no active bots exist.

Extended `BotOrchestrator` to import the `Suggestion` model and fetch suggestion data from Redis for each user session. Integrated these suggestions into the `BotResponse` payload, ensuring clients receive relevant suggestions alongside bot messages.

These changes improve bot selection flexibility and enrich the response data with contextual suggestions.
