Fix: CLI dashboard showing multiple cookie entries for same cookies

[ayushnirwal]

Description

There were multiple copies of same copies with the only difference being a ".". This PR fixes that issue by adding a "." in front of all the cookie domains missing that. This approach is inspired by how the Chrome browser internally handles cookie domain.

Testing Instructions

• Analyze the website - https://rtcamp.com.
• There should not be multiple entries of the same cookie
