Added migration toolkit for transfering data from firebase to supabase

[HelloSniperMonkey]

Description

This PR introduces a Firebase Migration Toolkit designed to simplify and streamline the migration process from Firebase to other backend-as-a-service (BaaS) providers. The toolkit automates the transfer of authentication data, Firestore database entries, and storage files while ensuring data integrity and minimal downtime.

Currently, the toolkit supports Supabase as a migration target, with plans to add more providers in the coming weeks. The goal is to make the transition seamless, reducing manual effort and minimizing disruptions for developers moving away from Firebase due to its limitations and pricing concerns.

Key Features

• Automated Migration: Transfers Firebase authentication, Firestore data, and storage files efficiently.
• Data Integrity: Ensures no data loss during migration.
• Extensible: Designed to support additional BaaS providers in future updates.
• Developer-Friendly: Reduces manual work and simplifies migration with a few commands.

Fixes #250

Type of change

• New feature (non-breaking change which adds functionality)
