Blockchain deposit methodology

Three endpoints from the original manual blockchain-funding flow are now deprecated:

• POST /cardholders/{cardholderId}/register-wallet-address
• POST /cards/{cardId}/deposit
• POST /wallets/{walletId}/deposit

What's replacing them: every card now automatically receives unique deposit addresses across 80+ blockchains and 3,000+ digital assets at the moment it's issued (returned as cryptoAddresses on the card object). Incoming digital-asset deposits are detected and processed straight-through with no registration or notification call required.

These endpoints remain functional for existing integrations, but new integrations should not use them.
