Deploy: Npcap is a one-time MANUAL install per cockpit (operator consensus)

Retire the bundled-silent-installer requirement: postinstall now detects an
existing Npcap service and moves on, warns clearly when absent, and still
honors a bundled deploy\npcap.exe if one is shipped. package.ps1 no longer
flags the missing bundle as a warning.
