Add schema selector to the editor toolbar for schema-aware databases
(PostgreSQL, SQL Server, Oracle). When a schema is selected, the backend
sets the appropriate search_path before executing queries so users no
longer need to write schema-qualified table names.
- First-time visitors see a password setup page instead of open access
- Password persisted to SQLite (env var DBX_PASSWORD takes priority)
- Add change password in settings dialog (Security tab, web only)
- Split settings dialog into Editor and Security tabs
- Argon2 hashing for all password storage
Replace all JSON file storage (connections, secrets, history, AI config,
conversations, sidebar layout) with a single SQLite database (dbx.db).
Auto-migrates existing JSON data on first launch, renaming old files to
.bak. Remove keyring dependency — passwords now stored in SQLite.
Introduce src-web (axum HTTP server) exposing all 43 database operations
as REST APIs with SSE streaming for AI, transfers, and SQL file execution.
Frontend adapts automatically between Tauri and HTTP backends via api.ts.
Includes password authentication, Docker packaging, and login page.
