Add anonymization support with --anonymize flag

[dcblogdev]

1. Configuration (config/dbsync.php)
   Added anonymize config array with examples showing how to map tables and columns to Faker methods
   Supports special syntax like bcrypt:password for hashed passwords

2. Command Flag (src/Console/DbSyncCommand.php)
   Added --anonymize (or -A) flag to the command signature
   Feature is off by default (opt-in only)

3. Anonymization Logic (src/Console/DbSyncCommand.php)
   New anonymizeData() method processes configured tables after import
   Uses Laravel's Faker library for realistic fake data
   Progress bar shows which table is being anonymized
   Error handling for each table (continues if one fails)
   Updates records individually to ensure proper data generation

Usage Example

// In config/dbsync.php
'anonymize' => [
    'users' => [
        'email' => 'safeEmail',
        'name' => 'name',
        'phone' => 'phoneNumber',
        'password' => 'bcrypt:password',
    ],
    'customers' => [
        'email' => 'safeEmail',
        'first_name' => 'firstName',
        'last_name' => 'lastName',
    ],
],

# Sync with anonymization
php artisan db:production-sync --anonymize

# Or use shorthand
php artisan db:production-sync -A
