Pull request overview

This PR adds step tracking to Bitcoin signer device actions, enabling consumers to monitor the progress of multi-step operations. Each device action now includes a step field in its intermediate values alongside the existing requiredUserInteraction field, providing more granular visibility into the state machine's progress.

• Adds step enums and types to three device action type definitions (SignPsbt, SignTransaction, GetWalletAddress)
• Updates device action implementations to set and maintain step values throughout state transitions
• Updates all corresponding test files to assert correct step values in intermediate values
• Includes minor refactoring for consistency (converting object returns to arrow function shorthand, simplifying array wrapping for actions)
