android: target Android 16 (API 36)

Play blocks updates from August 31, 2026 unless the app targets API 36.
Bump compileSdk/targetSdk to 36 in :app and :baselineprofile, and AGP to
8.10.1 -- 8.7.3 cannot build against API 36. Gradle stays at 8.11.1, which
is what AGP 8.10 requires.

Nothing in the app relies on the behaviours Android 16 changed: edge-to-edge
is already opted in via enableEdgeToEdge(), the manifest pins no orientation
or resizability, and the two bundled native libraries (graphics-path,
datastore_shared_counter) are already 16 KB page aligned.

Align the version with iOS (1.8.1, code 88) so the API 36 build can ship.
