feat(displays): clearer virtual-display preset names + descriptions

"Gaming rig" actually meant a dedicated/headless box you only ever stream from,
which confused users — rename it to "Headless box" and rewrite all five preset
summaries to be scenario-first and shorter (the console cards already show the
mechanics as badges). Updated across the host API summaries (mgmt.rs), the web
console labels (en/de), and the docs table + prose. The internal preset id
`gaming-rig` is unchanged (stable API / stored-policy / test contract).
