Onboarding: connection terminal and flags table

[talissoncosta]

Part of #7737. Extracts the verify console and flags table into prop-driven components with stories.

Scope

• Terminal: listening (checklist + typewriter + pulsing LISTENING) → connected receipt, driven by a status prop.
• Flags table: reuses product FeatureName / Tag / Switch; waiting / connected states; real Dev toggle.
• Stories for both states (no Onboarding: track first SDK evaluation received #7623 needed — prop-driven).

Done when

• Both are standalone prop-driven components rendered by the page.
• Toggle persists; no simulated SDK output.
• Stories cover listening / connected / waiting / toggle.
