feat: add firebase configuration and deployment scripts

This commit introduces Firebase configuration files (.firebaserc,
firebase.json) and updates the Makefile to include deployment
commands for different environments (dev, staging).

The .firebaserc file defines Firebase projects for development and
staging, along with hosting targets.

The firebase.json file configures hosting settings, including
rewrites and ignores. It defines hosting targets for the main app
in dev and staging, and a separate target for an internal launchpad.

The Makefile is updated to include:
- GCP project IDs for dev and staging.
- Environment detection (ENV variable).
- Conditional variables based on the environment (GCP_PROJECT_ID,
 FIREBASE_ALIAS, HOSTING_TARGET).
- Deployment commands for the launchpad and the main app.
- The build command now passes the environment variable to the
 frontend build process.

The internal launchpad is added to firebase/internal-launchpad/index.html
to provide quick access to application URLs and Firebase/GCP
consoles for different environments.

A patch script is added to inject the environment label into the
Dashboard page.

The index.html title is changed to KROW.

These changes enable streamlined deployment and environment
management for the KROW application.
