Stripe connection status

Stripe connections owned by the selected workspace with connectionPurpose (accounting, firm_payments, or subscription_links), live account health, charge capability, outstanding Stripe requirements, account mappings, and last sync. The all-connections response includes canConnectLinkingOnly for Sentinel when its default account is active. Pass integrationId for one connection and its recent sync log entries. Unmapped accounting accounts are repaired silently; subscription_links accounts never provision accounting mappings and are excluded from new payments and onboarding.
