feat(admin): Implement RPC endpoints for EAP API queries in Snuba Admin

[nachivrn]

• Implement new RPC endpoints in Snuba admin that lets Sentry engineers invoke the EAP API against production data.
• Add a page in Snuba admin that lets the user run those queries against whitelisted org / project ids

These changes enable authorized users to perform EAP API queries directly through Snuba Admin
