fix: Add input validation and OAuth client access control

- Add username validation (required, 3-50 chars, alphanumeric + underscore)
    - Add password validation (required, minimum 8 characters)
    - Add email format validation using regex
    - Add owner check in OAuth client update and delete operations
    - Allow admin users with wildcard permission to access all organizations
