Extract the Wi-Fi QR share card into its own omarchy.wifiqr panel plugin (#6598)

* Extract the Wi-Fi QR share card into its own omarchy.wifiqr panel plugin

omarchy-network-qr now leads with an iface/security/ssid meta line, so a
bare summon self-detects the connection and the plugin owns the whole
share flow. The network panel loses its overlay lifecycle: with no
centered card left inside it, the shadowed open/close collapses back to
the stock panel behavior, and the QR button just summons the plugin --
which a clone or third-party plugin can replace, like the speed test.

* Keep canceled QR and password runs from leaking into their replacements

Copilot review: the cancellation guards dropped in onExited while the
canceled run's collectors were still allowed to fire, so a stale stderr
could shadow a successful regeneration and a stale password could be
revealed under a new network's card. The guards now stay up until the
next run launches, good output settles any earlier error, and a bare
re-summon no longer inherits the previous card's SSID.
