Scaffold new /[locale]/soroban route and sidebar nav entry

[christabel888]

Context: No /soroban route exists today (confirmed against frontend/src/app/[locale]/) -- this is a genuinely new page, unlike the Network Dashboard which extends /network.

Where:

• New frontend/src/app/[locale]/soroban/page.tsx
• frontend/src/components/layout/sidebar.tsx -- add nav entry (coordinate with Restructure sidebar.tsx nav groups: Overview, Assets, Wallets, Soroban, Rankings, Validators, Explorer #175's broader nav restructure so this isn't done twice)

What to do:

• Scaffold the route with a basic layout; panels are added in Add Active Contracts panel to Soroban dashboard #166-Add New Deployments and Top Contracts table to Soroban dashboard #169.

Suggested approach:

1. This issue covers scaffolding the /soroban route plus all 4 panels (active contracts, contract calls, gas usage, new deployments/top contracts) -- treat it as "ship a working Soroban Dashboard," not just "create an empty page."
2. Coordinate nav entry placement with #34 rather than guessing at where it'll live in the final IA.
3. Backend chore(deps): bump zod from 4.3.6 to 4.4.3 in /frontend #23 (gas usage) may not have real data yet since it might require a schema change -- build that panel with an explicit "coming soon" state rather than blocking the rest of the page on it.

Watch out for:

• This is a genuinely new page with no existing scaffold to copy structurally from within this app for a dashboard page (as opposed to a data-table page) -- if a mobile equivalent (Stellar-Insightss/mobile#26) lands first, look at its data-fetching approach for consistency, even though the UI framework differs.

Definition of done:

• /soroban route exists and is reachable from the sidebar

[DEV-DESIGN6]

I’d like to take on this issue by building the Soroban Dashboard from the ground up, ensuring it integrates seamlessly with the existing application architecture and provides a solid foundation for future enhancements.

My implementation will include:

• Creating the new /soroban route with a clean, responsive dashboard layout.
• Adding the sidebar navigation entry while coordinating with the ongoing navigation restructuring to avoid conflicts or duplicate work.
• Implementing the four dashboard panels: Active Contracts, Contract Calls, Gas Usage, and New Deployments/Top Contracts.
• Displaying an explicit "Coming Soon" state for the Gas Usage panel if backend data is not yet available, allowing the rest of the dashboard to remain fully functional.
• Following existing frontend patterns for components, data fetching, and state management to keep the implementation consistent and maintainable.

I will deliver a production-ready Soroban Dashboard that is accessible from the sidebar, responsive across devices, well-tested, and easy to extend as additional backend functionality becomes available.
