feat(01-02): add data directory, server hooks, and verification page

- Create data/ directory with attachments/ subdirectory and .gitkeep files
- Update .gitignore to track .gitkeep but ignore database files
- Server hooks initialize database on first request
- Page server load fetches entries and creates test entry if none exist
- Verification page shows database status, entry count, and recent entries
