Fixes #4423

[Copilot]

Pull Request Overview

This PR fixes an issue where the withdraw button appeared disabled due to incorrect boolean attribute handling in Vue.js. The change ensures that when the withdraw button should be enabled, the disabled attribute is completely removed from the DOM element rather than being set to a string value.

Key Changes

• Updated the :disabled attribute binding to use proper boolean logic that removes the attribute when the button should be enabled

The expression !!(condition) || null is unnecessarily complex. In Vue.js, you can simply use the boolean condition directly: :disabled="userBalance.available < minWithdraw || blockedByTax". Vue will automatically handle the attribute presence/absence based on the boolean value.

Suggested change

	:disabled="!!(userBalance.available < minWithdraw || blockedByTax) || null"
	:disabled="userBalance.available < minWithdraw || blockedByTax"
