Swap Settings and Manage in navigation

[mapgie]

What changed

Settings and Manage swap places in the app's navigation:

• Settings now has its own item on the bottom navigation bar, in the spot Manage used to occupy (with the gear icon and "Settings" label).
• Manage is now the top-right icon on the home screen (the Tune icon), where Settings used to live.
• A Manage link is added as the first item in the Settings screen, so Manage stays reachable from Settings as well.

Notes

• The Home bottom-bar item now stays highlighted while the Manage screen is open, mirroring the previous relationship where Home stayed selected while Settings (its top-bar destination) was open.
• Both Manage and Settings remain in bottomNavRoutes, so the bottom bar continues to show on both screens.
• No en/em dashes in the new user-facing strings; the new "Manage" list item reuses SettingsNavItem, which already carries Role.Button semantics, so a11y_check.py passes.
• Adds a minor changelog fragment.
