fix: drop manifest screenOrientation portrait (#1171)

[pradhyumna186]

Summary

Removes manifest android:screenOrientation="portrait" from TreeTrackerActivity and ImageCaptureActivity so the app no longer declares orientation locks that conflict with Google Play guidance for large screens and Android 16+ behavior. Previous values are preserved as XML comments with context (see AndroidManifest.xml).

Fixes #1171

Short screen recording attached showing the app rotating between portrait and landscape on a Resizable emulator to see current behavior after removing the manifest lock.

Notes

• End users are still primarily phones in portrait; this change is to satisfy Play policy and avoid manifest restrictions on tablets / foldables. Follow-up UX polish for non-portrait layouts can be tracked separately.

As mentioned in the related issue, this will not be merged until we have proper support for landscape.
