feat(android): honor mediaCapturePermissionGrantType="deny" (AGE-378)

[alexz-phantom]

Android previously ignored the mediaCapturePermissionGrantType prop in the dApp browser WebView fork — the native setter was a no-op. Implement the minimal native enforcement the dApp browser contract needs:

• Persist the prop value in RNCWebChromeClient and propagate it through both the new- and old-architecture managers and RNCWebViewManagerImpl.
• Short-circuit RNCWebChromeClient.onPermissionRequest for deny: call request.deny() and return before reading requested resources, showing the site-attributed AlertDialog, or triggering an OS CAMERA/RECORD_AUDIO request.
• Any other value (including the default prompt) preserves existing Android behavior; iOS behavior is unchanged.
• Add a JVM unit test proving the deny short-circuit, plus the JUnit/Mockito test deps and testOptions to run it.
• Expose the prop on AndroidWebViewProps, update docs, and add a changeset.

Summary by CodeRabbit

• New Features

  • Added Android support for configuring how media capture permission requests are handled.
  • The deny option now blocks camera/microphone prompts on Android, while other values keep the existing prompt behavior.

• Documentation

  • Clarified platform support and behavior for media capture permission settings.

• Tests

  • Added coverage for denied requests and for preserving the existing prompt flow in other cases.

📝 Walkthrough

Walkthrough

This PR adds Android-native enforcement of mediaCapturePermissionGrantType="deny" in RNCWebChromeClient.onPermissionRequest, propagates the setting through RNCWebViewManagerImpl and old/new architecture RNCWebViewManager classes via a new React prop, adds unit tests and Gradle test dependencies, and updates TypeScript types, documentation, and a changeset.

Changes

Android deny media capture permission

Layer / File(s)	Summary
RNCWebChromeClient deny short-circuit android/src/main/java/com/reactnativecommunity/webview/RNCWebChromeClient.java	Adds a "deny" constant and field, a setter method, and an early-return guard in onPermissionRequest that calls request.deny() and skips the existing dialog/OS-permission flow when the grant type is "deny".
Prop wiring through manager layers android/src/main/java/com/reactnativecommunity/webview/RNCWebViewManagerImpl.kt, android/src/newarch/.../RNCWebViewManager.java, android/src/oldarch/.../RNCWebViewManager.java	Persists and forwards the grant type from RNCWebViewManagerImpl to RNCWebChromeClient, and exposes the mediaCapturePermissionGrantType React prop via @ReactProp in both architecture variants.
Unit tests and build test config android/build.gradle, android/src/test/.../RNCWebChromeClientTest.java	Adds testOptions and JUnit/Mockito dependencies, and a new test class verifying deny short-circuits the request while null/unknown grant types preserve the existing prompt flow.
TypeScript types, docs, and changeset src/WebViewTypes.ts, docs/Reference.md, .changeset/age-378-android-deny-media-capture.md	Adds mediaCapturePermissionGrantType to AndroidWebViewProps with JSDoc, updates IOSWebViewProps JSDoc, updates the reference doc's platform coverage and behavior notes, and adds a patch changeset.
