 The provider editor also accepts an optional `inputModalities` fallback: a nonempty array containing
 `text`, `image`, `audio`, or `video`. Exact per-model declarations take precedence. Invalid values
 are rejected on save; a malformed value in a hand-edited config loads as `["text"]` with a warning.
