Important

Stacked on #663 and depends on PostHog/posthog-android#908. posthog-android 4.0 removes RRStyle, so #663 won't compile for Android without this change.

💡 Motivation and Context

posthog-android 4.0 removes wireframe session replay (PostHog/posthog-android#908). Since screenshot frames are the only kind left, the internal RRWireframe now keeps only id, x, y, width, height, type and base64, and RRStyle is deleted. SnapshotSender passed style = RRStyle(), which only serialized an empty "style": {}.

This PR stops passing it. Android screenshot frames from Flutter now have the same shape as iOS 4.0 frames, which never sent style. The player doesn't read style for screenshots.

💚 How did you test it?

• Published posthog 7.0.0 / posthog-android 4.0.0 from chore!: remove wireframe session replay capture posthog-android#908 to a local Maven repo and ran ./gradlew :posthog_flutter:testDebugUnitTest from example/android against it: 57 tests pass, including SnapshotSenderTest and SnapshotSenderEncodingTest.
• Not run: on-device replay.

The Android screenshot constructor matches the trimmed native replay model, and omitting the empty style preserves player behavior. Native 4.x dependency availability and successful native builds/tests remain prerequisites for shipping.
