Implement Follow and Chat Features

Description:

In order to enhance user interaction on Skriza, we need to add the ability for users to follow each other and engage in chats. This will allow users to keep track of content from their favourite contributors and also engage in direct communication.

Acceptance Criteria:

• Users should be able to follow other users on Skriza.
• Following a user should cause their posts to appear in the follower's feed.
• Users should be able to initiate chats with other users.
• Chats should support real-time messaging, allowing for dynamic conversations.
• The system should handle potential errors effectively, including attempting to chat with non-existing users or follow a non-existing account.
