Improvements: End of the week edition

Create a PR attempting to address the following:

• Folder rearrangement
• Further deconstruction into components
• Reintroduces local storage cache for auto-detected assets to avoid extra API calls. Introduces a refresh button (with bad style) to 'force fetch'.
• Thanks to the local storage, implements clear 'state transition functions' that facilitate switching between steps 1-2-3-4
  • From asset selection to hacked address selection is made possible
  • User can remove an 'unsignedTx' in the bundling phase and go back to asset selection, and their changes in the bundling phase will apply. For example, if they removed a transaction at this step, it will be removed in the previous step as well.
  • Adding a custom call was adding the call to the "assets" but didn't "select" the call as an "asset". As a result, user needed to both add the custom call and then select it. This PR corrects this behavior.
• Check added for when hacked account and safe account are the same
• Minor renamings
