Display user's own posts on the feed screen

[Shruti-1910]

Description:

Currently, the feed screen displays posts from other users but does not include posts made by the current user. It is important for users to see their own posts in the feed to ensure they are aware of their contributions and interactions within the app. The app should display the user's own posts alongside posts from other users on the feed screen.

Expected Behavior:

• The feed screen should include posts made by the current user, displayed in chronological order along with posts from other users.
• The user's own posts should be visually consistent with other posts but may include subtle indicators to denote ownership.

Acceptance Criteria:

User Interface:

• The user's own posts should appear in the feed, integrated seamlessly with posts from other users.
• The posts should be displayed in chronological order, regardless of the author.

Functionality:

• The feed should fetch and display posts from both the current user and other users.
• The logic for fetching and displaying posts should ensure that all relevant posts are included and ordered correctly.
• Any existing features (e.g., likes, comments) should function identically for the user's own posts.
