fix: multiple local blocking fixes

[AyakorK]

🎩 Description

Fix multiple issues that happened simultaneously :

1 - We couldn't create an application using docker because of a "db issues" which happened to be a migration that wasn't working properly anymore

2 - When we tried to edit an organization on local, so without docker, Secret Key was missing and it caused an error based on the authenticity of the organization

Testing

LOCAL tests (without docker) :

# 1. Generate Rails credentials
EDITOR="nano" bundle exec rails credentials:edit

# 2. Generate AR encryption keys and add them to credentials
bundle exec rails db:encryption:init
EDITOR="nano" bundle exec rails credentials:edit

# 3. Add stable SECRET_KEY_BASE to .env
echo "" >> .env && echo "SECRET_KEY_BASE=$(bundle exec rails runner "puts Rails.application.credentials.secret_key_base" 2>/dev/null | tail -1)" >> .env

# 4. Add the following entries to your global gitignore (~/.gitignore)
#    config/master.key
#    config/credentials.yml.enc

# 5. Initialize the database
DISABLE_DATABASE_ENVIRONMENT_CHECK=1 bundle exec rake db:drop db:setup

# 6. Start the server
bundle exec rails s

• Launch the /system view
• Try to edit an organization
• Make sure everything works correctly
