feat: address fixes, about page, event config enhancement

[alexdivadi]

This pull request introduces several new UI components and enhancements to the input widgets, improves theme consistency and density, and adds new routes to the application. The most significant changes include the addition of address autocomplete and switch input widgets, improved customization for date/time and text fields, and tighter, more compact theming across light, dark, and high-contrast modes.

New Input Widgets and Features:

• Added a new AddressAutocompleteField widget, enabling address search with autocomplete and integration with form fields. [1] [2]
• Introduced AnyStepSwitchInput, a reusable switch/toggle form field with label and help text support. [1] [2]
• Enhanced AnyStepDateTimePicker with options for disabling default initial value, setting date bounds, and allowing users to clear the field. [1] [2] [3] [4]
• Improved AnyStepTextField to support custom label and hint colors for better accessibility and consistency with the theme. [1] [2]

Theming and Visual Density:

• Refactored the theme in theme.dart to use tighter text scaling and height, and applied compact visual density and smaller tap targets for all themes (light, dark, high-contrast). This results in a more modern and space-efficient UI. [1] [2] [3] [4] [5]

Routing and Navigation:

• Added new routes for AboutPage and NotificationSettingsPage to the application's router configuration. [1] [2]

Widget and Codebase Cleanup:

• Renamed DropdownSection to DropdownText for clarity and updated related state class names. [1] [2]
• Ensured correct typing for the properties map in the shareContent function.

These changes collectively enhance the user experience by providing more flexible and accessible input components, a visually tighter and more consistent UI, and improved navigation structure.
