Ctrl+1..9 to jump to a tab by its current position (main window + Preferences)

Ctrl and a number selects the Nth tab as it currently appears — positions are live, so they follow
the user's tab reordering and the pan/EQ tab's show/hide. Handled in ProcessCmdKey on both the main
window and the Preferences dialog; focuses the tab strip afterwards so NVDA reads the new tab (like
Ctrl+Tab). Matches Andre's readout app. Manual updated.

Build clean; --selftest passes; deployed to both test folders. Held for next release.
