Switch oracle-rs to t8y2/oracle-rs fork with SYSDBA support.
Add sysdba field to ConnectionConfig and a checkbox in the
Oracle connection dialog to enable connecting as SYS with
SYSDBA privileges.
Refactor all database drivers, query execution, schema operations, and
business logic into a shared `dbx-core` crate. The Tauri desktop app
becomes a thin shell delegating to dbx-core, enabling future web and
CLI frontends to reuse the same core.
