Feature: Receive tab

This branch introduces the UI tab responsible for recording and showing the decoded message.

List of changes:
- created a UI based on design and implemented external assets
- created theme_assets.dart to allow managing the theme settings
- created receive_tab.dart with a few children widgets as a main Receive tab view component, but placed it inside main_page.dart, to prepare for the implementation of the next Send tab
- created receive_tab_cubit.dart to manage the Receive tab view
- created device_selector.dart - a widget that allows to select the input device on windows application, using win32audio package
- created a series of AnimationController widgets in receive_tab, that allow animated UI and respond to different states of the ReceiveTabCubit
- created outlined_icon.dart to allow outlining every icon
- implemented particle generator in decoded_msg_background.dart using the particles_flutter package
- added placeholder_test.dart to support GitHub workflows with private repo access config, in case tests are added in the future (placeholder can be replaced with real tests)
