* Hotspot captive portal: welcome page with the WROLPi's address
Devices that join the hotspot probe a fixed plain-HTTP URL to check for
Internet access. NetworkManager's shared-mode dnsmasq now resolves those
probe hostnames (and `wrolpi`) to the hotspot address via an include the
Controller writes when the hotspot starts, the probes land on the Controller
(port 80), and are redirected to /portal: "This is your WROLPi, its address is
10.42.0.1, open WROLPi / open the Controller".
Only the probe hostnames are hijacked so the hotspot keeps forwarding
everything else when the WROLPi has an uplink. The include is corrected and
the connection re-activated once if NetworkManager picked a non-default
subnet. Writing the include is best-effort; the hotspot starts regardless.
`hotspot.captive_portal` (controller.yaml, default true) toggles the probe
redirects and the include; like the other hotspot settings it applies on the
next hotspot start, so saving while the hotspot is up reports
restart_required and both Controller UIs say so. The status endpoint gains
the hotspot address and portal URL, shown in both UIs. repair.sh only
creates the include directory so a disabled setting survives upgrades.
Native only: Docker has no hotspot.

* captive portal: address review
* React: re-read the hotspot address whenever the HotspotToggle starts or
stops the hotspot, matching the fallback UI's refresh-on-status.
* A WPA3 start that reverts to WPA2 leaves the hotspot up, so it now gets
the captive portal address correction too.
* The corrective `nmcli connection up` logs a warning on a non-zero exit;
dnsmasq would otherwise keep the old address silently.
* HotspotStatusResponse.captive_portal defaults to true like everywhere else.
* Trim design narrative from the module docstring and React comments.
* The include-before-activate test now observes the include at the moment
of the `nmcli ... hotspot` call instead of inferring from call order.

* captive portal: never forward any record type for probe hosts
`address=` only synthesizes A/AAAA answers. iOS also asks for the HTTPS
record type; dnsmasq forwarded that upstream, Apple's answer aliased to
captive.g.aaplimg.com, and the phone fetched the genuine "Success" from
Apple instead of the portal. Each probe host now also gets `local=`, so
dnsmasq answers every type itself, and the CDN alias is a probe host too.
Observed with dnsmasq query logging on a hotspot with an eth0 uplink.

* captive portal: let acknowledged clients finish so the OS offers "Done"
A phone's sign-in sheet only shows "Done" once the OS re-probes and gets
the genuine success reply. The Controller now remembers each client (by
hotspot IP) that has loaded the portal page and answers its later probes
with the reply each OS expects (Apple "Success" HTML, Android 204, Windows
"Microsoft Connect Test", ...). The set is cleared when the hotspot
starts so a new session shows the page again.

* captive portal: acknowledge on Continue, not on view
iOS fetches the portal page in the background before opening the sheet,
then re-probes after the sheet's own navigation. Acknowledging on view
made that re-probe return "Success" as the sheet's content. Phones only
re-check the network (and offer "Done") after a full-page navigation, so
the welcome page now has a Continue button leading to /portal/continue,
which is the only place a client is acknowledged. The Continue page says
to tap Done and links to WROLPi and the Controller.
Also hijack clients3.google.com (older Android probe host).
