[BUG] Default Token for "Send" Button Should Be FLOW

[Peppermint1020]

Description:
Currently, when a user clicks the "Send" button on the homepage, the last used FT (fungible token) is set as the default token for the transaction. This behavior is inconsistent and can cause confusion. The default token should always be FLOW when the user navigates to the send page from the homepage.

Steps to Reproduce:

(1)Open the homepage.
(2) select a token other than FLOW and Click the "Send" button.
(3)Complete the transaction.
(4)Return to the homepage and click the "Send" button again.
Expected Behavior:
The FLOW token should be set as the default token on the send page every time the user clicks the "Send" button from the homepage.

Actual Behavior:
The previously selected FT remains as the default token when navigating back to the send page from the homepage.
