Improve test coverage for model-name-convert.mjs

This commit adds unit tests for several previously untested functions
in `src/utils/model-name-convert.mjs`. The goal was to address
feedback regarding test coverage for this module.

The following functions now have comprehensive unit tests:
- modelNameToValue
- getModelValue
- modelNameToApiMode
- getApiModesFromConfig
- getApiModesStringArrayFromConfig
- isApiModeSelected
- isUsingModelName
- getModelNameGroup
- getApiModeGroup
- isInApiModeGroup

Dependencies from `src/config/index.mjs` were mocked as needed to
facilitate testing various scenarios and input conditions for these
functions.

As a result of these additions, all 66 tests in the
`model-name-convert.test.mjs` suite pass. Code coverage for
`src/utils/model-name-convert.mjs` has increased to approximately
98% for statements and 100% for functions.
