Add Solana mainnet chain config entry (native SOL)

New pezkuwi-overlay chain entry mirroring the Tron/Bitcoin native-coin
config shape: solana:mainnet chainId, public mainnet-beta RPC endpoint,
Solana Explorer links, and a native SOL asset (9 decimals). New brand
icons (gradient chain icon + colored token icon) added alongside.
