Night tab tint, Dynamic Type, aurora alerts (!18)

- Tab bar: selected tab tinted red while the Sky tab is in night mode.
- Dynamic Type: fixed sizes replaced with text styles across the app (drawings excepted); Today summary wraps to two lines; draw-time readout only in Debug builds.
- Aurora alerts (opt-in, Settings): registers push token, 5° geomagnetic band and UTC offset; test-alert button; =POST /v1/devices/{token}/test= on the Worker (rate-limited).
- Privacy policy and App Store answers updated: alerts mean "Coarse Location" and "Device ID", not linked, not tracking.

Tests: =swift test= 37 pass, =node --test= 10 pass. End-to-end push check in the simulator follows the merge and deploy.

19| Coarse Location | Yes (5° geomagnetic band) | No | No | App Functionality |
20| Device ID | Yes (APNs push token) | No | No | App Functionality |
21
22- Precise location: used on device only, never sent.
23- Other network requests (backend, NOAA, NASA, image hosts) carry no
1924 identifiers.
2025- No analytics, advertising, accounts, crash reporting SDKs or tracking.
21- Revisit when aurora alerts ship: the push token, a 5° geomagnetic
22 latitude band and UTC offset are sent to the backend. That is
23 likely "Coarse Location" and "Device ID", used for "App
