Move AdminDashboard out of RoleDashboards.tsx

[jgupta05072003-code]

What this is for

RoleDashboards.tsx is a 3,100+ line file holding all 8 role dashboards. We're moving each one into its own file so the codebase is easier to navigate.

What to move

export const AdminDashboard (~405 lines) — the dashboard shown to State Admin-role users.

Steps

1. Create frontend/src/components/dashboards/AdminDashboard.tsx.
2. Cut the AdminDashboard component out of RoleDashboards.tsx into the new file, with whatever imports it needs.
3. Back in RoleDashboards.tsx, add: export { AdminDashboard } from './dashboards/AdminDashboard'; where it used to be.
4. Don't change any logic or JSX — copy it exactly as-is.

How to check your work

1. cd frontend && npm run lint — no errors.
2. npm run build — succeeds.
3. Run npm run dev, log in as a State Admin user, and confirm the dashboard looks and behaves exactly the same as before.

Part of #136.

Saw PR #228 is already open for this — leaving it with you, not touching it myself.

Could you get it merge-ready by end of day tomorrow (2026-08-20)? If you hit a blocker, just comment here rather than letting it sit.

@jgupta05072003-code Ma'am as said by you, can I work on this issue next ?

[jgupta05072003-code]

Approved — go ahead, Nitish. The PR that was open for this (#228) has been closed, so this is fully open for you now. Same ask as with #139: keep it a clean, isolated extraction of AdminDashboard out of RoleDashboards.tsx, verify it builds (tsc --noEmit + vite build) and click through it live before opening the PR.
