Merge branch 'compose': Compose UI overhaul

Every screen moves from XML layouts, Views and Fragments to Jetpack
Compose with Material 3, in one MainActivity with a NavHost: the list
with breadcrumbs, search, pull to sync and multi-select; the entry view
with OTP countdown; the editor with generator sheet and folder picker;
setup (welcome, git server and clone, SSH key, PGP keys); settings, git
config, commit log and proxy; and the autofill picker, publisher
warning and decryption prompts. LaunchActivity stays the only exported
activity. Fixes found on the way reach master with it, among them
symlink-safe deletes, the proxy user name, screen lock gated switches,
the Android 14 app lock and screen lock prompts, and the autofill
passphrase cache rule. The View-era dependencies and view binding are
gone; Material Components (Views) stays for the git dialogs.
