android-native: real-server login by default, readable CJK text, 16 KB pages

- FreeType: add the cff/psaux/pshinter modules (from the pinned 2.13.3
  tarball, same sha256). Android's only CJK font is the CFF2
  NotoSansCJK-Regular.ttc, which the TrueType-only build could not open,
  so every Chinese glyph drew as a box.
- Font oversample rounds the UI density up: Android's 1760x800 UI on a
  2376x1080 screen is 1.35, which rounded to 1x bilevel glyphs stretched
  1.35x. Now 2x anti-aliased glyphs are scaled down. macOS 2.0 unchanged.
- MainActivity: a launcher start (no intent args) opens the login screen
  against 192.168.21.203 instead of auto-logging into the in-process fake
  server; explicit args still select the fake-server smoke flow.
- build-android-native.sh: ANDROID_SUPPORT_FLEXIBLE_PAGE_SIZES=ON for SDL3
  and libmain (LOAD alignment 0x1000 -> 0x4000), with a stamp that
  rebuilds a cached pre-flag SDL3. Clears Android's 16 KB compat warning.
