The bar-null-shell-null-typeof-function ternary guarded against our own
shell missing a method it always defines. bar?.shell?.firstPartyServiceFor()
handles the only real case, delayed bar injection, in one line. The
typeof checks that probe genuinely third-party plugin objects stay.

Each panel's hero on/off toggle (Tailscale, Dropbox Wi-Fi, Bluetooth,
network, audio mute) now has a reachable "header" cursor section, a focus
ring around the hero icon, Enter/Space activation, a letter shortcut, and
hover parity. The hero is inset by heroRingPad so the ring stays inside
the Flickable/ScrollView clip box instead of being cut off.
Bluetooth and audio get a virtual "header" section above their device
sections, so the adapter/mute can be toggled by keyboard even when no
device rows exist. Network repurposes its previously dead header section.
For the PanelHero-based panels (Tailscale, Dropbox), route panel state
through the wrapper's `header` id: inside a PanelHero iconComponent `root`
resolves to PanelHero, not the Panel, so `root.headerHasCursor` and
`root.setHeaderCursor()` silently referenced the wrong object.
