[SaiShanmukkha]

This PR updates docs/01-quick-start.md to include an explicit database migration step in the local setup instructions. Without running migrations, users may encounter database errors. Adding this step ensures a smoother setup process and prevents potential issues.

Changes:

Updated docs/01-quick-start.md to include database migration instructions.

Why?

• Running migrations is necessary for the database schema to be up to date.
• Prevents users from encountering database-related errors during local setup espicially during inital signup.
