redesign: modern indigo UI, new app icon, edge-to-edge theme

App icon: deep indigo-to-violet gradient background with white sync arrows;
replaced flat #2196F3 with layered adaptive icon.

Theme: disabled dynamic color; rich indigo/teal/amber Material3 palette;
edge-to-edge with transparent status bar; tighter typography letterSpacing.

HomeScreen: colored left accent bar per status; URL-decoded SAF paths;
relative timestamps (Just now / N min ago / N hr ago); indigo status pills;
FilledTonalButton empty state.

PairDetailScreen: hero StatusBanner with large icon and relative time;
InfoCard as bordered grid with icon backgrounds; colored dot event timeline;
URL-decoded local path display.

SettingsScreen: section headers with primary left bar; AccountCard with
primaryContainer icon backgrounds; Security/About in bordered cards.

Bump version to 1.0.13 (code 14).
