chore: bump backend version to 1.0.49

The email_data column in PostgreSQL is a JSON type that auto-parses
the data, while SQLite stores it as a string. Updated the code to
check if email_data is already an object before attempting to parse.

This fixes the "Unexpected token o in JSON at position 1" error.
