Bug: File Validation Defaults Cause Security Concerns
The file validation trait has inconsistent default config values. enable_dangerous_validation is disabled by default when not configured, but enable_extension_validation and enable_mime_validation default to true. This changes the previous opt-in behavior, potentially enabling validations unexpectedly and creating a security risk by silently skipping critical dangerous file checks.

Bug: Inconsistent Error Handling in Validation Methods
The validatePDFFile method adds errors using an indexed array append ($errors[]), which differs from other validation methods in this trait that use an associative key ($errors['message']). This inconsistency can lead to unexpected error array structures, potentially breaking downstream error handling that expects a consistent 'message' key.

Bug: Default Validation Setting Insecure
The enable_dangerous_validation check in validateFile lacks a default true value, unlike other validation configurations. This results in dangerous file validation, like rejecting archive files, being disabled by default, which creates a security vulnerability.
