refactor(models): add fillable attributes for database configuration options

Add explicit fillable attributes to Service and all Standalone* database models
for new configuration options: public_port_timeout, enable_ssl, ssl_mode,
is_log_drain_enabled, is_include_timestamps, and custom_docker_run_options.

Add tests to MassAssignmentProtectionTest to verify these attributes are
properly protected by mass assignment protection across all relevant models.
