[Task]: Improve enable blind signing popup for ledger

### Task description

Most transactions (except basic transactions with no metadata/tag) require blind signing to be enabled on the ledger app. When a user hasn't enabled this, sending a transaction requires a prepared output to be stored, so that FF can resend it automatically whenever the user has enabled blind signing.

This is problematic, since wallet.rs doesn't expose prepare outputs for all types of transactions (e.g.: Governance, mint NFTs, ...).
*Might be fixed if https://github.com/iotaledger/iota-sdk/issues/104 gets implemented and released.*

Alternatively, FF can detect whether blind signing has been enabled and show a popup to enable this on certain tabs (Dashboard/NFT/...). We would need a design for a popup that warns the user that they should enable blind signing before attempting to perform a transaction.
