The first beta release of the 3.x branch for the Lottiefiles Field module. This major update brings support for the new `.lottie` format, upgrades the underlying animation player, and introduces seamless Media Library integration.

⚠️ **Important:**
Please test this beta release in a development or staging environment before deploying to production. As this is a major version jump from 2.x, please verify that your existing Lottie fields and media entities upgrade smoothly.

### What's New in 3.x:
* **DotLottie (`.lottie`) Support:** Added full support for the new, highly optimized `.lottie` file format alongside traditional JSON files.
* **Upgraded Lottie Player:** Transitioned to the latest Lottie Web Components/Player (`@lottiefiles/dotlottie-web`), completely removing the need for obsolete local player library files.
* **Media Library Integration:** Lottie animations now preview properly within the Drupal Media Library view mode.
* **Form & Validation Improvements:** Improved Media Form labels, synchronized attributes, and fixed form validation errors.
* **Enhanced Field Options:** Added more customization options for how the player displays and behaves (playback controls, speed, background, etc.).

*Please report any bugs or issues in the module's issue queue.*
