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.

+   * Blue zones are used to `capture' hints and force them to a common

+   * A poor-man error facility.
+   *
+   * This code being written in vanilla C, doesn't have the luxury of a
+   * language-supported exception mechanism such as the one available in
+   * Java.  Instead, we are stuck with using error codes that must be
+   * carefully managed and preserved.  However, it is convenient for us to
+   * model our error mechanism on a Java-like exception mechanism.
+   * When we assign an error code we are thus `throwing' an error.
+   *
+   * The preservation of an error code is done by coding convention.
+   * Upon a function call if the error code is anything other than
+   * `FT_Err_Ok', which is guaranteed to be zero, we
+   * will return without altering that error.  This will allow the
+   * error to propagate and be handled at the appropriate location in
+   * the code.
+   *
+   * This allows a style of code where the error code is initialized
+   * up front and a block of calls are made with the error code only
+   * being checked after the block.  If a new error occurs, the original
+   * error will be preserved and a functional no-op should result in any
+   * subsequent function that has an initial error code not equal to
+   * `FT_Err_Ok'.
+   *
+   * Errors are encoded by calling the `FT_THROW' macro.  For example,
+   *
+   * {
+   *   FT_Error  e;
+   *
+   *
+   *   ...
