feat: Improving User Experience with Flexible Sync Account Choices

[XRG999]

Feature description

Currently, Android and iOS devices use different accounts for cloud synchronization, and there's no option to change this. It is recommended to allow users to choose their preferred sync method, such as:

1. Google account login
2. Apple account login
3. WebDAV-based backup

This would provide greater flexibility and a more seamless cross-platform experience.

Additionally, in some regions—such as mainland China—Google services are inaccessible, making cloud backup and synchronization on Android devices difficult. Therefore, it is strongly recommended to add customizable backup options, such as:

1. WebDAV
2. Apple ID
3. Other flexible backup methods

This would greatly enhance usability and accessibility for users in restricted network environments.

It's also a single point of failure to be forced to rely on e.g. Google or Apple, not to mention not being able to decide where (geographically and legally) the backup of your 2FA codes are stored.

It doesn't exactly feel great to store the 2FA for your Google account IN your Google account, in case you manage to lock yourself out completely (from the Google account and your Android-phone) and have to start from scratch on a new device. How will you get access to any of your 2FA-codes for any of your other accounts, if they are all in 2FAS and the only backup is locked away in Google Drive...?
