[FIX] aiml: Replace hardcoded domains with dynamic rendering for media content #25

• Replace all hardcoded domain references with dynamic resolution to ensure portability and long-term maintainability of the project.
• Domains currently hardcoded in codebase and some DB fields:
  • media.mrsoni.me
  • url.mrsoni.me
  • chat.cse-aiml.tech
  • cse-aiml.tech
  • students.cse-aiml.tech
• These domains are expiring or subject to change; dynamic handling is required for:
  • Media files
  • Job descriptions (PDFs)
  • Faculty photos
  • Any user-accessible URL content
• Also update database tables where these domains are statically stored in fields.

Work on this is in progress under the main-dynamic-domain branch.
Updates will include dynamic handling for all listed domains across both the codebase and relevant DB fields.
