vite dev only proxied /api and /auth, so /admin/login hit the SPA root
layout, re-ran loadSession, got 401, and redirected back to /admin/login
with an ever-nesting returnTo. Proxy /admin/login to the backend (which
owns it before the SPA fallback) and guard redirectToLogin against
re-entering /admin/login.
Replace the only emoji-as-icon (the back-arrow on project detail) with
the Icon component (new arrow-left glyph).
Add scripts/dev-bootstrap.ts for seeding a local Silo (stub probes) so
npm run dev can start on a fresh dev DB.
Run `prettier --write .` across all source files. Changes are purely
formatting: trailing commas, line wrapping at 120 chars, import
reordering, and CSS whitespace. No logic changes. Verified with
`prettier --check .` and `svelte-check` (0 errors, 0 warnings).
