Debanjum Singh Solanky 5294693e97 Style message as speech bubbles on chat page of web interface
- Wrap messages into speech bubbles
  - Color messages by khoj blue, sender grey
  - Add those standard protrusions to the speech bubbles for fun

- Align bubbles left or right based on sender
  - messages by khoj are left aligned, message by self are right aligned

- Put message metadata like sender and time under speech bubble
  - use data-* attribute and ::after css pseudo-selector for this

- Update renderMessage func to accept time param, remove unused type_ param
