[BUG] Correct upper helper text in inputs coloring

[stackingsaunter]

Current upper helper text in inputs is black in both light and dark theme (currently used only for range amounts defined by LNURL).

This element should have different colors:
Light theme: gray-700
Dark theme: neutral-400

Hi, I'm not able to see the text whose style needs to be fixed. @stackingsaunter can you please tell how do I regenerate this issue in my local setup??

[stackingsaunter]

@Pratik-A-N you can see them by pasting those LNURL invoices into Send
