feat: add contentprotectionerror player event on all platforms

[tvanlaerhoven]

Summary

Adds a new contentprotectionerror player event forwarded from the native THEOplayer SDKs on Web and Android. iOS bridge wiring is in place but the native listener is deferred until the iOS SDK exposes PlayerEventTypes.CONTENT_PROTECTION_ERROR (not available in THEOplayerSDK-core 11.5.0).

TypeScript API:

• PlayerEventType.CONTENT_PROTECTION_ERROR = 'contentprotectionerror' added to the enum
• ContentProtectionErrorEvent interface with an error: ContentProtectionErrorObject payload
• ContentProtectionErrorObject carries errorCode, errorMessage, and optional DRM-specific fields: url, status, statusText, response, systemCode
• DefaultContentProtectionErrorEvent implementation class + NativeContentProtectionErrorEvent native bridge interface

Platform forwarding:

• Web: WebEventForwarder listens on 'contentprotectionerror' from the Web SDK, maps errorObject fields (code, message, url, status, statusText, response, systemCode) into DefaultContentProtectionErrorEvent
• Android: PlayerEventEmitter registers PlayerEventTypes.CONTENTPROTECTIONERROR, forwards errorObject.code and message via PayloadBuilder.error()
• iOS: Bridge property (onNativeContentProtectionError) registered in THEOplayerRCTBridge.m, THEOplayerRCTView.swift, and THEOplayerRCTMainEventHandler.swift. Native SDK listener deferred — PlayerEventTypes.CONTENT_PROTECTION_ERROR does not exist in THEOplayerSDK-core 11.5.0.
• THEOplayerView.tsx: onNativeContentProtectionError callback wired in the render method

Follows the same pattern as existing error events (ErrorEvent, ChromecastErrorEvent).

🔍 iOS callback plumbing added but no native listener attached (deferred)

The iOS changes add the bridge property (ios/THEOplayerRCTBridge.m:50), the handler property (ios/THEOplayerRCTMainEventHandler.swift:33), and the setter (ios/THEOplayerRCTView.swift:473-477), but no player.addEventListener for content-protection errors is registered in attachListeners(). This matches the PR's stated intent that the iOS native listener is deferred until the SDK exposes the event type, so this is intentional and not a runtime bug (the prop is set but simply never invoked). Reviewer should confirm a follow-up ticket exists to wire the actual listener once the iOS SDK supports it.
