refactor(ui): relocate SearchBar to shared SearchInput component (#784)

* refactor(theme): consolidate design system, remove legacy theme

* fix(navigation): use qualifiedName strings for FlowHost saved state

KClass references aren't serializable and can't survive
rememberSaveable across process death. Use qualifiedName strings
instead so the seeded-stack comparison works after restoration.

* refactor(ui): relocate SearchBar to shared SearchInput component

Move the currency-selection-local SearchBar into a shared, reusable
SearchInput in ui/components. The placeholder is now a parameter,
the shape is CircleShape, and the icon tint follows the theme.

* fix(navigation): use qualifiedName strings for FlowHost saved state

KClass references aren't serializable and can't survive
rememberSaveable across process death. Use qualifiedName strings
instead so the seeded-stack comparison works after restoration.
