SECURE DB ACCESS

[RonaldCrb]

We need to secure the Firebase DB access. credentials are stored in git.

Acceptance

• pass the credentials as environment variables in the vercel platform
• setup database access rules
• test if we can use complex symbols in passwords

NOTE: firebase credentials are safe to include in the frontend code, however the auth password for the editor user is really sensitive and we should set it up in vercel directly. ive also reviewed the credential rotation procedure and the level of security of the passwords and it looks good
