fix(web): add missing loading and error states to MfaPromptBanner, Step1Identity, MobileSummaryClient

- MfaPromptBanner: silently hide on query error (non-critical advisory banner)
- Step1Identity: show skeleton placeholders while blueprint list loads
- MobileSummaryClient: add error state with retry button for dashboard queries
