Android 16 KB page size support via Qt 6.10 upgrade

[Copilot]

Google Play requires all apps targeting Android 15+ to support 16 KB memory page sizes (enforced from May 31, 2026). Qt 6.10 adds native built-in support for this, making manual workarounds unnecessary.

Changes

• android/CMakeLists.txt

  • Bump required Qt version 6.9 → 6.10 (native 16 KB ELF segment alignment baked in)
  • Remove manual -Wl,-z,max-page-size=16384 linker flag — now handled by Qt toolchain automatically

• android/android/AndroidManifest.xml

  • Remove android.page_size.compat property — this was a memory-wasteful compatibility shim allowing 4 KB-aligned code to run on 16 KB-page-size devices; superseded by properly aligned libraries from Qt 6.10
