Cleanup approve transaction review

[jpuri]

Fixes: #6159

The task was about extracting out tooltip component from ApproveTransactionReview component but I found that these components were actually not being used. Thus I delete them from code.

QA Steps:

• The PR only removes un-used code, a check can be done to ensure that gas tooltip on confirmation pages work as before.

It seem isSigningQRObject isn't passed to the ApproveTransactionReview component and so has no value. So yeah, lgtm. Great find, @jpuri

can we add some unit tests for this?

In a spot check I am I encountering an issue with spending approvals when using Keystone. After tapping approve, the button becomes disabled but the QR modal fails to open and present the composed transaction (to be scanned with Keystone).

iPhone 13 mini
iOS 15.6.1

Steps to reproduce:

1. Import SRP
2. bind with Keystone
3. Be on testnet or change to it (Sepolia)
4. Open test dapp
5. tap Create Token under Send Token (patience required here)
6. Add token to wallet and Transfer tokens (may not be required steps)
7. tap Approve tokens
8. Tap Approve
9. Note absence of QR

Hey @gantunesr , @plasmacorral : thanks a lot for helping with this. @plasmacorral : reported that this PR indeed has issue with QR scanning flow. I have updated the PR to remove QR code related cleanup. I will create a separate PR for cleaning that up.

From QA changes look good @jpuri . The tooltip is working as before in the different flows (Send ETH / Send token / Contract Interaction ..) and in different networks

PR can be merged. Whenever I get the Keystone, I can QA the other changes.

PS Thank you @plasmacorral for doing an initial QA on the QR code part !

Just want to confirm no issues observed with Keystone approval in commit 99fa02b on the same iphone I previously tested with.
