Expand hardware wallet integration coverage

[Nanle-code]

Summary:
Hardware wallet support is valuable, but the current feature set should be validated more thoroughly to ensure reliability.

Why this matters:
Hardware wallet compatibility matters for real-world developer adoption and security-sensitive workflows.

Proposed work:

• Add test coverage for hardware wallet integration paths
• Validate fallback behavior when hardware dependencies are unavailable
• Improve documentation for supported hardware flows

Acceptance criteria:

• Hardware wallet paths are covered by automated tests
• Failure behavior is clear and predictable
• Contributors can work on this feature with confidence
