[Tx flow] Errors should be cards

[iamacook]

Bug description

The errors shown in the sign/execute areas are currently "embedded" in parent cards, but they should be their own top-level ones.

Steps to reproduce

1. Connect to a Safe as a non-owner.
2. Try to create a transaction.
3. Observe the error.

Expected result

The error is it's own "top-level" card.

Obtained result

Errors are embedded within cards.

@ElizabethOgbee, I'd suggest tackling issues labelled as "good first issue" instead. We are still actively developing this.

The issue is still relevant - https://www.figma.com/file/cMDccuR9aZFqAiBd4dKsKg/Transaction-flow?type=design&node-id=1-7111&mode=design&t=1BX1Smn9y8gv4Wo2-4

I think, errors alerts should belong to the relevant places in the UI. This particular error is displayed before a user is about to confirm or execute a transaction, so it makes sense that it is a part of this block.

Good point, closing then. 👍
