Add TablePlus Windows packaging: input manifest, PowerShell
install/uninstall scripts, and outputs. The install script runs the Inno
Setup installer silently with /VERYSILENT /SUPPRESSMSGBOXES /NORESTART
/ALLUSERS; the uninstall script locates the Inno Setup uninstaller via
registry and runs it with silent args. apps.json was updated to include
TablePlus and a new outputs/tableplus/windows.json was added with
version 7.1.2, installer URL, sha256, and script references.
