fix: stale types test and unreachable ralph full-reset API path

- Remove tests for createSuccessResponse and ErrorMessages which were
  removed/made private during the type system refactoring (15 failures)
- Fix RalphConfigSchema to accept 'full' string for reset field,
  matching the route handler's fullReset() code path
