feat: Material You design system rewrite — Phases 1–4

Complete UI/UX rewrite of hermes-mobile with Material You design system.

Phase 1: Color/Theme/Type/Shapes/Spacing/Motion tokens
Phase 2: HermesScaffold, StateViews (skeleton/empty/error), SearchBar, StatusBadge, ToggleRow
Phase 3: Bottom nav + drawer navigation with NavigationController
Phase 4: All 17 screens rewritten with HermesScaffold and Material You patterns

Closes PR #3.

+ * Motion tokens — duration, easing, and spring specs.
+ *
+ * Design intent (ui-ux-pro-max §7):
+ *  - Micro-interactions: 150–300 ms
+ *  - Complex transitions: ≤ 400 ms
+ *  - Never exceed 500 ms
+ *  - Enter: ease-out (decelerated), Exit: ease-in (accelerated)
+ *  - Exit shorter than enter (~60–70 %)
+ *  - Spring physics for interactive elements
+ *  - All animations must be interruptible
+ *
+ * Access via `LocalMotion.current` in composables.
