fix: bitcoin receive, AIUI pointer input, electrs self-heal, OTA timeout

- LND wallet: request correct address type so receive-address generation
  no longer 400s
- AIUI/app session: on-screen pointer can click + type into app content
  (incl. app store search); "open in new tab" opens the phone browser;
  mobile credential modal centered instead of full-height
  (remote-relay.ts, AppSession.vue, AppSessionFrame.vue, AppIconGrid.vue,
  openExternal.ts, WebViewScreen.kt) + remote-relay tests
- health_monitor: electrs auto-recovers from a corrupt index and shows a
  percent/block-height progress screen while reindexing (useElectrsSync.ts)
- update.rs: drop retired tx1138 secondary mirror (one-time migration);
  longer download timeout for slow connections
- CHANGELOG: v1.7.90-alpha notes
- tests/release/run.sh: harness tweaks

 # Changelog
 
+## v1.7.90-alpha (2026-06-13)
+
+- Generating a Bitcoin receive address works again — the wallet now requests the correct address type, fixing the "400 Bad Request" error when creating an address.
+- In the companion app, the on-screen pointer can now click into apps and type — including the app store search box — instead of clicks and keystrokes not reaching app content.
+- "Open in a new tab" from the companion app now opens the app in your phone's browser, instead of doing nothing. The normal mobile browser keeps working as before.
+- The login/credentials pop-up on phones is once again a centered, properly sized window rather than stretching the full height of the screen.
+- The Electrum server now recovers on its own if its index ever gets corrupted, and shows a clear progress screen (with percent complete and block height) while it builds its index, instead of a blank or broken page.
+- Software updates are more reliable on slow internet connections — downloads are given much more time to finish before giving up.
+
 ## v1.7.89-alpha (2026-06-12)
 
 - The AI assistant looks the way it always did again: no extra back button or close button on phones, and the desktop view fills the whole screen without a gap at the bottom.
