Add Event Marking UI to Audio Plugin

[this-Aditya]

Description

Implement a UI for the audio plugin that allows interviewers to add event markers during audio recordings. This feature aims to enhance the ability to label specific events quickly during interviews.

Requirements

1. Button UI:

   • Add 5 buttons labeled 1 to 5 for event marking.
   • Each button should capture the timestamp and associated event name/ID when pressed.

2. Functionality:

   • The event markers should be configurable.
   • Events should be defined in a configuration page or via remote config to ensure quick access.
   • Store and display the last event data for reuse if needed.
   • Upload the events using a schema (RADAR-Event-Marker) that can be reused in other scenarios.
   • This feature is intended for marking events quickly, such as special questions or responses of interest.

Does this event marking need to be present specifically for the audio plugin, or for the complete application, or both? For example, should we add 5 buttons for the audio plugin and 1 button in the main Activity connected to the Application Plugin for complete application event marking?
