Improved progress display

Previously, the progress bar updated only after completing an entire table.

For large tables such as LIBARC, this could make the application appear to have stopped responding.

Phase 10 updates the interface while rows are being exported.

+# Phase 28 — Front-screen charts
+
+- The application opens on the Dashboard instead of the SQL editor.
+- A Dashboard toolbar button returns to the performance dashboard from anywhere.
+- Six colour-coded Swift Charts panels are embedded above server counters: queries/sec, connected threads, running threads, slow queries/sec, bytes received/sec, and bytes sent/sec.
+- Charts use actual MySQL SHOW GLOBAL STATUS readings and refresh every 5 seconds while the administration screen is open.
+- The first rate value requires two successful samples; no synthetic data is used.
+- Retains the Phase 27 SQL-based schema editor and the existing Trends window for other administration pages.
+- Build and live MySQL verification must be performed on macOS with Xcode.
