Signify difference in item unavailability reasons

[sman591]

There are two reasons we disable items:

• User cannot afford item
• Item is unavailable

However:

• The first user-actionable (add money to your account) while the second isn't (only by a drink admin)
• Both are shown in the UI with pink text.

If the error is user-actionable, it should stay highlighted in pink, while if it isn't actionable, it should be gray like the rest of the text.

Maybe even let the user tap on the user-actionable items, just to see an info popup.
