✨ bidirectional sync

[MB901]

Hi, thank you for this addon!

I’ve made some improvements to enhance functionality and usability:

• Added the ability to sync files from the remote server to Home Assistant (bidirectional sync).
• Removed the unused remote_folder variable.
• Updated folder naming conventions: switched from source/destination to local/remote to better reflect the purpose when using pull/push options.

Testing:

• Verified the sync process in both directions (local-to-remote and remote-to-local).
• Ensured that removing the remote_folder variable does not break existing configurations.

Let me know if you have any questions or need further changes.

Thanks!

Some minor comments from my side ;)

And it seems the linter picks up the old config folder. It's optional to fix that. If its not done in your PR, I will do it before release.
