wallet balance stale prices

[Viterbo]

Fixes #542

Description

The text explaining the price was changed but not as big as it was proposed because it was too big and created a super long tooltip. Then a hardcoded number was refactored for a constant

Test scenarios

• Go to balance page
• check the staked token balance. It has a tooltip with the new text.
