Add native SOL send and account info for Solana, using the card's Ed25519 key. Transaction building and serialization are delegated to solders; the card signs the raw message bytes and the 64-byte signature is grafted onto the message to produce the broadcastable transaction. - wallet/solana.py: Ed25519 address derivation (base58 of the raw key), JSON-RPC client (balance/blockhash/broadcast), transfer-message building and transaction assembly, and SolanaValidator - command/solana.py: "solana send" and "solana config" commands - command/options/solana.py: argument parsing, address and network validation - card/info.py: show SOL address and balance in the info table - config/enums: default "solana" config section and SolanaNetwork enum - register the solana command in the factory Bump cryptnox-sdk-py to >=1.0.5 (Ed25519 key derivation/signing) and add solders>=0.27.0.

Add the Solana command and wallet backend (send/transaction flow, address validation), enum/config/factory wiring, and CLI options; repoint BTC mainnet to blockstream.info and add base58/solders deps. Align signing with SDK v2.0 SIGN, with amount bounds, confirm-before-sign, and network/endpoint handling. Drop the dead old_key local in config.py so flake8 passes without a workflow ignore.
