[codex] Fix iOS WebSSH input capture

[ciallothu]

What changed

• Added an iOS-specific input capture path for the WebSSH WKWebView/xterm terminal so soft keyboard text, IME commits, backspace, Enter, Tab, arrows, Esc, and hardware Ctrl/Alt input are forwarded to the terminal WebSocket.
• Kept the terminal WebView mounted while connecting and buffered early terminal output until xterm is ready.
• Applied the iOS chart animation setting consistently to load and ping charts.
• Restored the executable bit on apps/android/gradlew so README/CI Gradle commands can run directly.

Why

The iOS terminal could connect, but xterm keyboard input in WKWebView was unreliable: Enter could be observed while normal typed characters did not reach the WebSocket.

Validation

• git diff --check
• Local iOS build could not run in this environment because xcodebuild is unavailable.
• Local Android tests reached Gradle but failed because no Android SDK is configured locally; GitHub Actions installs the SDK.
