The model picker (api/config.py:7308-7314) places the singular ``model``
field first, then appends unique IDs from the ``models`` catalog with
dedup. The Providers card was doing the opposite — dropping the singular
model entirely when a non-empty catalog existed.
This caused a silent disagreement: the picker showed the sticky default
model first, while the Providers card omitted it. Verified empirically
with ``model: sticky-default, models: {Best, Fast}`` — picker returned
the sticky model, card did not.
Now the card uses the same sticky-before-plural ordering as the picker:
singular model first (stripped), then _configured_model_ids appended
with dedup.
Updated tests:
- test_singular_model_appears_first_before_dict_models (was
test_dict_models_ignore_legacy_model_field): now asserts sticky-first
ordering instead of exclusion
- test_whitespace_and_duplicate_keys_normalized: updated for sticky-first
prepend
