[Feature] Admin dashboard: auth gate

[collinsezedike]

Summary

Add an admin-only auth gate in front of a new admin dashboard route: connect a wallet, read the vault contract's get_admin(), and only render the dashboard if the connected wallet's public key matches. Otherwise show a clear blocked state, not a silent redirect.

Motivation

The vault's admin currently has no UI for operational visibility (keeper health, vault state, recent admin actions), only stellar contract invoke calls or digging through GitHub Actions logs. This is the foundational piece the rest of the dashboard depends on.

Proposed Solution

• New route, e.g. /admin.
• On mount: if no wallet connected, show the "Admin access" connect screen (see Screenshots above).
• On connect: read get_admin() for the vault contract (needs a small off-chain reader added to coordinator.ts, mirroring the existing read-only helpers there) and compare against the connected publicKey.
  • Match: render the dashboard (built in the follow-up issues).
  • Mismatch: show the "Not authorized" blocked screen (see Screenshots above), which shows only the connected wallet's address, not the real admin address, deliberately, so the page doesn't hand out a ready-made phishing target to every unauthorized visitor.
• Re-check on wallet change/disconnect, matching the pattern useWalletStore's revalidate() already uses elsewhere.

Scope

Field	Value
Area	Frontend, SDK
Protocol affected	None
Network	Both
Breaking change?	No

Acceptance Criteria

• /admin renders the connect screen when no wallet is connected
• /admin renders the blocked screen when the connected wallet doesn't match get_admin(), showing only the connected wallet's address
• /admin renders the dashboard shell when the connected wallet matches
• Re-validates on wallet change/disconnect
• Matches the app's existing dark theme (#0d1117/#161b22 panel colors, border-gray-800, emerald accent), screenshots above show the exact spacing/colors expected

Additional Context

First of three admin-dashboard issues (auth gate, then observability panels, then the admin action history feed). Design reviewed and approved before filing; screenshots above.

I’d like to work on this issue because it addresses an important area of the project and presents a great opportunity to make a meaningful contribution. I’m particularly interested in delivering a solution that is reliable, maintainable, and aligned with the project’s existing architecture and development standards.

I have experience working across software development, including backend and frontend development, APIs, databases, testing, DevOps, and blockchain-based applications. I’m comfortable understanding existing codebases, identifying the root cause of issues, implementing clean and scalable solutions, and writing thorough tests to prevent regressions.

My approach would be to first understand the existing implementation and project conventions, then develop the solution in a focused and incremental way. I’ll ensure the changes are well-tested, documented where necessary, and do not introduce unnecessary complexity or break existing functionality. I’m also committed to clear communication, responding to review feedback, and delivering a polished contribution that provides real value to the project.

I want to build the admin auth gate so the team stops using GH logs for vault ops.

Experience: Next.js, Stellar SDK, Wallet auth. Built similar admin gates before.

Plan: readVaultAdmin() in coordinator.ts + /admin with Connect/Blocked/Authorized states + wallet revalidate. 24hr PR.
