Studio: confirm saved Hugging Face token with a tick (#6630)

* Studio: confirm saved Hugging Face token with a tick

Pasting a token and clicking away saved it silently with no feedback.
Show a green tick in the field once a non-empty token is committed and
the input still matches the stored value, so the save is visible. Adds
the tokenSaved label to the en and zh-CN locales.

* Studio: let clicks pass through the saved-token tick

The decorative tick sat over the input and swallowed clicks, so clicking
it would not focus the field. Add pointer-events-none so clicks reach the
input; drop the now-unreachable title and keep an aria-label via role=img.
