feat: expose orthographic camera projection

[balderfer]

Description

Filament already supports orthographic cameras through Camera::setProjection(Camera::Projection::ORTHO, ...), but react-native-filament currently only exposes the perspective helpers through the JS camera wrapper.

This PR bridges that existing Filament API so React Native callers can configure an orthographic projection without dropping down to native code.

Changes

• Adds camera.setOrthographicProjection(left, right, bottom, top, near, far) to the native Camera wrapper.
• Registers the new method with the JSI hybrid object.
• Adds the method to the RNFCamera TypeScript interface.

Testing

• Ran yarn check-all from package/.
• Verified C++ formatting ran after installing the missing clang-format local dependency.
• Verified ESLint and TypeScript completed successfully.
