Fix multi-selection: selectedKeys exposed as StateFlow, collected in
FilesScreen so checkboxes and highlights update correctly on every tap.
fileKey() made public so UI can check membership without ViewModel calls.
Icon: white cloud body with two cyan/teal circular sync arcs (AutoSync
style), deep blue-to-teal gradient background.
Security review clean: no hardcoded credentials, cleartext blocked by
network_security_config, allowBackup=false, path traversal guards in
place on both server responses and local resolution.
