Swap button enabled and approval not shown after account switch on swap page

[VolodLytvynenko]

Problem:

After switching from Account 1 (which has enough assets and approved ERC-20 tokens) to Account 2 (which has fewer assets and non-approved ERC-20 tokens), the "Review Swap" button remains enabled, and the user can proceed to the confirmation page, even though Account 2 does not have enough assets to complete the transaction. Additionally, the approval button is not displayed for Account 2, despite the ERC-20 token being unapproved.

Steps:

1, Recover a user with two accounts:

• Account 1 has an approved ERC-20 token.
• Account 2 has an unapproved ERC-20 token and fewer assets than Account 1.

2. Go to the swap page using Account 1.
3. Enter a valid value that is sufficient for Account 1 but insufficient for Account 2.
4. Switch to Account 2.

Actual Result:

• The "Review Swap" button remains enabled, and the user can proceed to the confirmation page despite insufficient assets in Account 2.
• The approval button is missing for Account 2, even though the ERC-20 token is unapproved.

Expected Result:

• The "Review Swap" button should be disabled after switching to an account with insufficient assets.
• The approval button should be displayed for Account 2 to allow the user to approve the ERC-20 token before swap proceeding.
