Allow choosing the transaction explorer in the Studio #380
Description
Hey, it’d be great if the Dev team could update the Studio frontend so users can pick their default transaction explorer -- from options like Solana Explorer, Helius Orb, Solana Beach, Solana.FM, or SolScan.
Could work as a simple CLI flag (like --explorer helius-orb) or even just a button or dropdown in the header on the site.
