fix: resolve lint warnings for AddJavascriptInterface, SetJavaScriptEnabled, WrongConstant

- D3SView.java: Add @SuppressLint for SetJavaScriptEnabled and
  AddJavascriptInterface. JavaScript and the JS bridge are required
  for 3DS payment flow; only trusted ACS pages are loaded.
- D3SRegexUtils.java: Replace static imports with qualified
  Pattern.compile(), Pattern.DOTALL, Pattern.CASE_INSENSITIVE
  so lint can verify the flag constants.

Fixes #8
