Fix Timestamp issue in chat interface

[Aastha-1411]

Closes: #7
This PR addresses the issue with incorrect timestamp display by ensuring the time shown is based on the user's local time, not the server’s. The app now correctly renders local timestamps both locally and after deployment.

Changes Made:
Replaced the old timestamp logic with one that considers the user's local timezone using st.context.timezone_offset. This ensures that the time displayed is accurate for the end-user, not just the server's timezone (e.g., UTC on Streamlit Cloud).

I verified the change by deploying the project myself on community cloud to check if .
it is making chnages as per the given time. You can see the image below.

I was chatting with the bot on 7:04 PM only. So its working fine.

That's great, @Aastha-1411 you've done a great job❕But:

1. The convo delete button doesn't appear in your screenshot, which means you haven't pulled the latest changes. Pull it at first, as one PR has recently been merged.
2. After doing that, link this PR to the issue which you created. It is unlinked.

I've checked this deployment link of yours: talkheal-kfiantnh6xkhtd3tzbg5bd.streamlit.app
And it doesn't show the delete buttons beside the conversations.

Whilst the latest changes will have this:

It maybe that your pulled changes weren't resolved properly, or maybe they were omitted totally after pulling, or maybe some logical error is hindering the delete functionality.

I hope you now understand. Correct me if I'm wrong about your deployment link (if you have any other latest deployment).
