feat: Add VerticalFloatingToolBar component and navigation

This commit introduces a new `VerticalFloatingToolBar` composable and integrates it into the application's navigation.

- **New Component**: Created `VerticalFloatingToolBar.kt` which implements a vertical floating toolbar with several icon buttons (Download, Favorite, Add, Person, ArrowUpward) and an overflow menu.
- **HomeScreen Update**:
    - Added a new `HomeItemData` entry for "Vertical Floating ToolBar" with a `Tune` icon.
    - Added a new navigation parameter `onNavigateToVerticalFloatingToolbarRoute` to `HomeScreen` and its invocation.
    - Updated the icon for "Floating ToolBar Example" from `Handyman` to `AutoMirrored.Filled.Subject`.
