Bug-fix and polish release.
What's new
- First-launch power-saving notice. A new splash info screen explains the app's power behaviour: switching away fully freezes the waterfall/spectrum to save battery (resumes in a second or two), and after 30 s on screen they slow down (toggleable in the menu). The full background freeze is by design and can't be disabled.
- Smarter resume from background. Returning to the app shows a calm "Reinitialising" notice while the waterfall comes back, instead of a misleading "Connection lost". It's gated on the live audio stream — a true disconnect (audio also dead) still shows "Connection lost", and if audio keeps playing but the spectrum genuinely fails to resume you get a clear prompt to reconnect or pick another instance.
- Home-bar swipe fix. Swiping up from the home bar to leave the app no longer nudges the tuning.
- Zoom MIN/MAX fix. The menu's MIN / MAX buttons (zoom fully out / fully in) now work — they previously did nothing — and the zoom row no longer reflows when the VFO is locked.
- In-app changelog updated to include the 5.1.2 iOS 26/27 audio fix and 5.1.3 changes.
