Add backup to Google Drive

[Angus-repo]

This PR implements the functionality requested in #1208 and #3296.
Thanks to the preparatory work completed by @vanelsberg in PR #3487, this PR is able to support automatic export of settings.

This feature allows users to select a cloud directory from the maintenance page. The original AAPS directory has been renamed to Local Directory; for first-time use, users are still required to specify the local path.
Users can independently decide whether logs, settings, and user entries should be stored in the cloud. The settings feature also supports importing settings from the cloud.

Due to slower cloud import performance, only the latest 5 settings entries are displayed at a time. If needed, users can manually load the next 5 entries.

Settings export can be combined with Automation: once the pump is enabled, settings are automatically exported to the selected cloud directory.
(Note: users are still required to manually enter their password once every four weeks.)

The main functionality is complete. Please help test this and provide feedback. Thank you!

are you sure it's a good idea to store log out of local storage. it's changing a lot

[Angus-repo]

The logs are still stored locally (in EXT_FILES_DIR used by logback). Only when exporting will the export location be determined based on the user’s selection. To avoid any misunderstanding, I adjusted the wording and have updated the images.

Great to see to his PR!

PR merged with dev, phone updated without issues, Did not encounter any issues on functionality.
Well done @Angus-repo!

Only feedback I have:
on initial Google authentication, "AAPS-CI" was mentioned. Could confuse user. Is this intentional?

Will run this on my main phone the coming days/weeks for more "field" testing.
TODO: test new installation, restore settings.

[Angus-repo]

@vanelsberg see AAPS-CI because it was created using the same website for the Google OAuth2 application. I will apply for an update to change the name and the icon.

Optimize cloud directory prompt message(Sync updated first-page display)

[vanelsberg]

PR does great and merges OK with current dev. No issues until know. Top!

@Angus-repo: Feature request?
In general, I have settings stored locally and use cloud as a backup. As is now we have local or cloud.
Unless this would need a lot a code changes, could we have both?

Yes :-) Thanks! This works great.
Exporting to cloud or local works without issues.
Selecting both "local" and "cloud" for preferences also works as expected.

FYI: I'm running latest dev (FullRelease, daily builds) with your PR merged on my daily driver phone.
Did not encounter any issues!

[vanelsberg]

This PR is still going strong for me. Imho it's complete and done? Ready for merging with dev.

I’ve changed this PR to Review status. If there are significant conflicts with the upcoming 4.0.0 version or if architectural adjustments are required, please tag me and I’ll make the necessary changes.

Note: The name and logo on the Google sign-in page are still under Google’s review. Once approved, they will take effect automatically without any code changes, so the sign-in page message can be ignored for now.
