[Hardware Wallet] Add Satochip support (NFC smartcard)

[Bastien-Satochip]

By integrating Satochip smartcard signing option, your mobile wallet could:

• Offer hardware-grade security without requiring users to manage complex hardware wallets.
• Differentiate your product in a competitive wallet market with a premium security feature.
• Unlock new user segments, including security-conscious individuals, enterprises, and high-net-worth users.
• Create opportunities for new revenue models, such as premium tiers, bundled hardware, or enterprise offerings.

We envision a collaborative approach that may include:

• SDKs and technical documentation for wallet integration
  --> We already provide several SDKs such as: Swift SDK, Android SDK, React-Native SDK
• Joint definition of UX and signing flows
• White-label manufacturing and provisioning options
• Ongoing support, maintenance, and feature evolution
