feat: improve tablet and large-screen navigation layout

[mykh-hailo]

Summary

This change adapts the main file browser and several activities for tablets and wide layouts (typically sw600dp / w600dp) by using a persistent navigation column next to content instead of relying only on the sliding DrawerLayout pattern used on phones.

Closes: #14871

DrawerActivity is updated so drawer behavior works when the root layout is not a DrawerLayout (e.g. ConstraintLayout with a fixed-width nav region). Alternative layouts under layout-sw600dp align Compose, Navigator, Contacts preferences, Synced folders, and Upload list with the same idea. files.xml is refactored to support the sidebar + content structure and to keep ViewBinding (FilesBinding / drawer_menu) consistent. TrashbinActivity and toolbar_standard are adjusted for the new structure. New sidebar.xml and resource tweaks (bools, dims) support the tablet configuration.

Technical notes

• DrawerActivity: Centralizes “menu layout” handling; drawer toggle, ActionBarDrawerToggle, and related APIs run only when the root is a DrawerLayout; optional hamburger visibility when the layout does not use a sliding drawer.
• Resource qualifiers: layout-sw600dp (and related values-*) provide wide-screen layouts without affecting default (phone) resources.
• File display: files.xml + sidebar.xml structure; FileDisplayActivity updated as needed for binding / initialization.
• Consistency: Trashbin and toolbar spacing tweaks aligned with the new app bar / content arrangement.

@alperozturk96 Could you please check my PR for the tablet view?
Any feedback and advice is always welcome

Hello, thank you for your PR.

Since these changes affect multiple screens, they will require thorough testing. To help the review process, could you please limit the scope to a single screen with minimal changes for now? Once that is reviewed and validated, we can proceed incrementally.

Additionally, please:

• Exclude any .salive files from the PR (I updated gitignore)
• Remove comments that restate obvious information (e.g., field descriptions that are self-explanatory)
• Follow camelCase naming conventions (e.g., sidebarQuotaView instead of mSidebarQuotaView)

Thanks again for your contribution.

@alperozturk96 Thank you for the updates.
All the code that handles the sidebar and drawer menu is implemented DrawerActivity, and it adapts to different screen sizes. I've also added the sidebar layout to the XML files where needed.

I initially tired to create a patch that only affects FileDisplayActivity, but it turns out that all related changes are required, except for the XML layouts. However, if the XML layouts for other activities are not updated, it may cause error during testing.

Could you advise on a simpler way to handle this so it's easier to test?

@alperozturk96 I'd appreciate it if I can continue to work this issue.
