(feat-extension and eduaid_web):Add Speech-to-Text Feature and Fix Copy Button Issue

[Description:](#99 ) We need to add a speech-to-text feature to our application and fix the issue with the copy button not working in both the extension and the website. The speech-to-text feature should use the Web Speech API to convert spoken words into text. The copy button should copy the text content to the clipboard.

Steps to Reproduce:

- Open the application (both extension and website).
- Try to use the copy button to copy text to the clipboard.
- Observe that the copy button does not work as expected.

Expected Behavior:

- The speech-to-text feature should convert spoken words into text and display them in the text area.
- The copy button should copy the text content to the clipboard.
