Fix duplicate default projects and add one-time cleanup

[xaelophone]

Summary

• prevent repeated first-login seeding by keying initialization off stable user id
• make default seeding idempotent for Welcome and Essay projects
• add one-time per-user duplicate cleanup for default projects with conservative safety checks
• run cleanup on both app root redirect and ProjectSwitcher first fetch so direct project routes are covered

Safety

• cleanup only targets default titles: Welcome to Hermes, What Does a Tool Owe You?, My First Project
• deletes only exact content duplicates created within 15 minutes
• skips groups containing any published/slugged project
• stores a local one-time marker per user per browser

Validation

• npx eslint apps/web/src/App.jsx apps/web/src/pages/FocusPage/ProjectSwitcher.jsx
