Adds a login page for the dashboard app: Django-side login/dashboard views with next redirect validation and login_required, plus React components (login form, user menu, shadcn primitives) that call the existing /graphql login/logout mutations directly via fetch.

Error Handling

• login-form.tsx: top-level GraphQL errors (payload.errors) are surfaced verbatim as form errors (errors.map((error) => error.message)). Unlike the WrongEmailOrPassword branch, which uses a hardcoded friendly message, this path shows whatever message the server returns for unexpected/unhandled exceptions, which risks leaking internal error details to users.
• nav-user.tsx logOut(): no error handling — if the fetch throws (network error) or response.ok is false, nothing happens: no loading state, no user feedback, dropdown just closes. The user may believe they logged out when they didn't. Also, it only checks response.ok and ignores GraphQL-level errors in the body, so a 200 response with a failed mutation is still treated as success... actually it doesn't even redirect on error, it silently no-ops.

Minor

• Both login-form.tsx and nav-user.tsx duplicate near-identical raw fetch("/graphql", ...) boilerplate; consider extracting a small shared GraphQL helper now that there are two call sites.
• dashboard/login views don't set Cache-Control: no-store. Since Inertia embeds the authenticated user's name/email directly in the rendered HTML response, using the browser back button after logout could show a cached copy of the dashboard page.
