Feature: Skip Option During Transaction Review

Overview:
Introduces the ability for users to skip any item during the transaction review process and directly navigate to the approval menu. This feature is implemented by invoking the new view_review_init_progressive function:

view_review_init_progressive(tx_getItem, tx_getNumItems, app_sign_eth);
view_review_show(REVIEW_TXN);

User Flow:

1. Review Message:
   • Item 1
     • Page 1
     • Page 2
     • Page 3
2. Continue/Skip Menu:
   • Right Button: Continue to the next item.
   • Left Button: Go back to previous item.
   • Both Buttons: Skip to the approval menu.
3. Review Subsequent Items:
   • Item 2
     • Page 1
   • Continue/Skip Menu
   • Item 3
     • Page 1
     • Page 2
4. Approval Menu:
   • Final step to approve and sign the transaction.

Compatibility:

• Supported Targets: All except STAX and FLEX.
• Purpose: Mimics the review flow used in app-ethereum for EIP-191 personal messages.

Implementation Details:

• Custom Callback Handler:
  • Created to overcome limitations of the UX_STEP_CB macro.
  • Handles right/left and both button presses.
  • Re-initializes the UI stack to support multiple options on the same screen(nanox/nanos+).

Compilation Flag Consideration:

• Current Status: Feature is enabled by default when calling view_review_init_progressive.
• Future Consideration: Evaluate the need for a compilation flag to toggle this feature as needed.
