* fix: scope mobileconfig DNS to Wi-Fi only via OnDemandRules
Without OnDemandRules, iOS applies the DoT profile globally —
cellular DNS breaks when the phone leaves the LAN.

* feat: phone setup QR code in dashboard header
- Add /qr endpoint serving SVG (uses existing qrcode crate, svg feature)
- Header popover: QR on desktop, direct download link on mobile viewports
- Only visible when [mobile] enabled = true in config
- Expose mobile.enabled and mobile.port in /stats response
- Lazy-load QR on first click, dismiss on outside click

* fix: add Cache-Control to /qr, re-fetch QR on each popover open
Cache-Control: no-store prevents stale QR after LAN IP change.
Remove qrLoaded flag so the QR always reflects the current IP.

* fix: add iOS install steps to phone setup popover
iOS shows "Profile Downloaded" with no guidance. The popover
now includes the 3-step install flow including the buried
Certificate Trust Settings toggle.
