feat(ui): add individual model delete buttons across all providers (#13271)

### What problem does this PR solve?

Added the option to delete models individually from providers.
For additional context, see
[issue-13184](https://github.com/infiniflow/ragflow/issues/13184)

### Type of change

- [x] New Feature (non-breaking change which adds functionality)

Note: when deleting a selected model, it leaves the full model name as
text as seen here:
<img width="676" height="90" alt="image"
src="https://github.com/user-attachments/assets/c11c7c1b-3f2a-4119-b20c-bb8148a8ad16"
/>

If attempting to use ragflow with that deleted model, ragflow will throw
an unauthorized model error as expected.
I left it like that on purpose, so it's easier for the user to
understand what he deleted and that he needs to replace it with another
model.
