[Duplicate]: Disable auto-sync toggle when logged out

[resolvicomai]

Description

Fixes the Settings sync control so logged-out Studio users cannot enable Auto-Sync without a session.

The switch now:

• reads the current auth state from the user store
• renders unchecked and disabled when the user is logged out
• shows the sign-in guidance requested in the issue
• guards the toggle handler so it does not write the sync preference or start sync work without an authenticated user

Fixes #64

Type of Change

• 🐛 Bug fix (non-breaking change which fixes an issue)
• 🧪 Tests (adding or updating tests)

Validation

• npm run test:contracts -w @veriworkly/studio -- tests/contracts/sync-section.contract.test.tsx
• npm run test:contracts -w @veriworkly/studio
• npm run lint -w @veriworkly/studio
• npm run format -w @veriworkly/studio
• NEXT_PUBLIC_BACKEND_URL=http://localhost:8080/api/v1 npm run build -w @veriworkly/studio
• git diff --check

Attempted npm audit signatures, but npm registry resolution failed before audit with ETARGET No matching version found for @types/node@25.8.0.

Pushed a follow-up for the failing Quality & Testing check. The failure was from root Prettier on two existing docs/readme files; while replaying the remaining CI path locally, I also fixed the blog platform source import so npm run build can resolve the generated Fumadocs source under Turbopack.

Validated locally:

• npm run lint
• npm run format
• npm run test:contracts -w @veriworkly/studio
• DATABASE_URL=postgresql://dummy:dummy@localhost:5432/dummy npm exec -w @veriworkly/server -- prisma generate --schema=prisma/schema.prisma
• CI-like npm run build with the workflow dummy env vars
• git diff --check
