-/**
- * Admin UI for AI provider selection and API-key management.
- *
- * - Dropdowns set the active provider per capability (text / image / audio /
- *   video). Selecting "auto" tells the backend to try paid providers first
- *   and silently fall back to free providers on quota / billing errors.
- * - API-key inputs are write-only — the backend never returns a key value;
- *   we only render a "saved" badge based on `keys_set[<name>]`.
- * - Changes persist to `ir.config_parameter` and take effect on the very
- *   next request (no caching), so admins can flip OpenAI -> Mock without
- *   restarting Odoo.
- *
- * Mounted as the fourth tab on `/admin/ai/prompts` so the user keeps a
- * single "AI" surface in the admin nav.
