Enhance setup script with robust credentials, environment, and dynamic database configuration

[Copilot]

The setup script has been enhanced to handle common configuration issues that developers encounter when setting up the application, particularly around Rails credentials, environment variables, and database naming customization.

Key Improvements

1. Robust Credentials Management

The setup script now intelligently handles the scenario where config/credentials.yml.enc exists but config/master.key is missing. When this situation is detected, users are presented with three clear options:

• Provide existing master.key: Enter the 32-character hex key with format validation
• Create new credentials file: Safely removes the old encrypted file and generates a fresh one
• Skip for now: Allows manual setup later with clear instructions

2. Dynamic Database Configuration

The setup script now prompts users for a custom project name and automatically updates the database configuration to use that name as the prefix instead of the hardcoded "rapid_rails_inertia_js". This allows developers to customize their database names during setup:

== Database Configuration ==
Current database prefix: rapid_rails_inertia_js

Enter your project name (or press Enter to keep 'rapid_rails_inertia_js'): my_awesome_app

Updating database configuration with project name: my_awesome_app
✓ Database configuration updated with prefix: my_awesome_app

Features include:

• Interactive project name prompt during setup
• Input validation (must start with letter, contain only lowercase letters, numbers, underscores)
• Automatic replacement of database names across all environments (development, test, production)
• Backward compatible - keeps default naming if no project name is provided

3. Automatic Environment File Setup

The script automatically creates a .env file from .env.example if it doesn't already exist, ensuring developers have the necessary environment configuration template.

4. Enhanced User Guidance

Added comprehensive messaging throughout the setup process with clear status indicators (✓, ⚠, ℹ) for better visual feedback, step-by-step instructions, and references to example files.

5. Improved Documentation

Updated the README with detailed quick start guide, manual setup instructions as fallback, credentials troubleshooting section, and clear environment variable documentation.

Testing

All existing tests pass (32 examples, 0 failures), RuboCop style checks pass, Brakeman security scan shows no warnings, and frontend linting passes. The database name replacement logic has been thoroughly tested.

The enhanced setup script maintains full backward compatibility while providing a much more robust and user-friendly experience for new developers setting up the application.

Fixes #22.

Added dynamic project name configuration to the setup script. The script now prompts users for a project name and automatically replaces the database prefix in config/database.yml with the provided name.

Key features:

• ✅ Interactive prompt during setup: "Enter your project name (or press Enter to keep 'rapid_rails_inertia_js')"
• ✅ Input validation (lowercase letters, numbers, underscores only)
• ✅ Automatic replacement of database names across all environments
• ✅ Backward compatible (keeps default if no name provided)
