Fix schema migration gaps for v3
Critical fixes to match Dnote v3 server schema: 1. Remove separate accounts table - In v3, email/password were merged into users table - Migration now joins accounts with users during migration 2. Add missing FullSyncBefore field to users - This field exists in v3 server but was missing from migration 3. Update migration logic - Users migration now LEFT JOINs with accounts table - Email and password are migrated directly to users table - Remove migrateAccounts function (no longer needed) 4. Update tests to match new schema - Verify email/password on users instead of separate accounts - Add FullSyncBefore verification - Tests pass ✓ This ensures the migrated SQLite database matches the v3 server schema exactly, preventing any compatibility issues. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
