docs(#359): donate line, richer Discord w/ links, web set to coming-soon

- Release notes: added a Support Offband donate section (offband.org/donate,
  verified live), framed toward funding iOS.
- Discord: fully rewritten, richer per-feature copy + real links (download/
  release, project site, donate). Was thin and link-less.
- Web handling: offband.app is NOT deployed (404) and untested, so pulled the
  live web claim from the platform list, changelog, and Discord; replaced with
  'browser version coming soon'. dev.offband.app works but is not a release URL.

Gate passes; no em-dashes in the new copy.

Part of #160. Agent: SapphireCompass (session 8d755b5e)

+A ground-up interface redesign, a real database under the hood, GIFs that work across every MeshCore client, and hands-on control of your radio's RF front end. This is also the first Offband release built, signed, and shipped to every platform automatically.
 
-🗄️ **New storage engine.** Your data now lives in a real SQLite database instead of scattered preference files. Existing messages and contacts migrate automatically on first launch, nothing gets dropped, and full message history is preserved. On desktop it no longer fights with OneDrive/Documents sync.
+🎨 **A brand-new interface.** The headline feature. There's a new **left rail** you open from the hamburger button and can **pin open**, so it lives right alongside your chat instead of covering it. Your channels live in the rail and switch **in place**, so you never lose your spot. Map toggles, Disconnect, and Settings all found sensible new homes, and the back button finally behaves.
 
-🧭 **New navigation.** A hamburger drawer you can **pin open**, with the channel list built in and in-place channel switching so you never lose your place. Map layer toggles and a contacts filter rail moved into the panel, and the back button finally behaves.
