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
Closes: #16141

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.
