fix(packaging/windows): Windows 11 22H2 floor + tray install task + stale console-port fixes

The OS floor is now enforced at install time (MinVersion=10.0.22621 with an
explanatory [Messages] override): pf-vdisplay is built against IddCx 1.10, and
on Windows 10 (incl. LTSC) / Win11 21H2 the device fails start with Code 10
STATUS_DEVICE_POWER_FAILURE (field-reported). Docs (site requirements/install/
windows-host pages + README) state the floor; new docs-site Security page.

Installer also gains the trayicon task (punktfunk-tray.exe file + HKLM Run key,
post-install launch as the signed-in user, upgrade taskkill + uninstall
--quit/taskkill choreography before file deletion), and the wizard/cleanup
text/port sweeps move off the stale :3000 web-console references to :47992
(cleanups sweep both for upgrades from old installs).
