Modernize Pi components using Entity Descriptions

[Louis983257]

This PR updates the Speedport integration for compatibility with Home Assistant Core 2025.6+ and future versions.

✅ Replaces deprecated method async_forward_entry_setup() with async_forward_entry_setups()
✅ Removes async_create_task() misuse
✅ Tested on:

• Home Assistant Core 2025.6.1
• Speedport Smart 4 Typ A

New Update 30.01.2026

I have updated the integration to use the modern Entity Description pattern. This improves code maintainability and ensures compatibility with current Home Assistant standards.

Changes made:

binary_sensor.py: Migrated to BinarySensorEntityDescription.
button.py: Refactored to use ButtonEntityDescription.
device.py & switch.py: Updated internal logic to support the new entity structure and improved device handling.
Code Cleanup: Removed deprecated constants and streamlined the initialization process for these components.
These updates ensure that the Pi-related entities are future-proof and follow the latest best practices.

I confirmed this works! I hope this can be merged.. 🤞

I tested by updating the file directly and then restart the HA.

Even though I'm not deeply involved in the details of what exactly you've adjusted, I'd like to thank you for further developing this.

I've just integrated the five modified files and everything looks good, with no error messages.

Hi @Andre0512

I’ve updated this pull request with the latest changes.
Everything is now working correctly with current Home Assistant versions.

If you have a moment, I would really appreciate a review.
If you prefer this PR to be split into smaller parts or want changes to naming/structure, just let me know — I’m happy to adjust anything quickly.

Thanks for maintaining this integration! 🙏
