fix(android): generate missing a11y service resources in plugin

Plugin referenced @string/accessibility_service_summary +
@xml/accessibility_service_config in AndroidManifest but never created the
underlying resource files. EAS Cloud prebuild --clean exposed this — local
dev worked because resources were sometimes already there from previous builds.

- withStringsXml: adds accessibility_service_summary string (DE)
- withDangerousMod: writes res/xml/accessibility_service_config.xml at prebuild
- Config flags match native service (TYPE_WINDOW_CONTENT_CHANGED + STATE_CHANGED,
  canRetrieveWindowContent for URL-bar reading)
