[cashtab] Remove the avalanche finalized message/icon in the tx history expanded area

Summary:
There already is an avalanche status check icon very visible on all the txs. This extra finalization message just adds redundant information, and the animation catches the eye which contribute to the "bloated" feeling of the cashtab home page.

This has the side effect of moving the interaction icons from the right to the left. I don't feel this is a problem but this can be fixed easily if needed.

Test Plan:

npm run test
npm run start
