Delete one of the caller's own connections (destructive)

Removes the integration_connections row globally. Intent is destructive: 'I never want to use this credential anywhere again'. Refused with 409 connection_pinned while an admin pin or an org default (enforced or soft) names the connection: those sets carry no foreign key, so the dead id would fail every consuming run. An admin removes it from the pin(s) or default first. A member pin does not block the delete. The caller's own member pins and schedule overrides drop the connection in the same transaction — a pin it empties is removed (the cascade falls back), and a schedule override it empties drops that integration and disables the schedule (its job is removed) rather than let it fall back unattended; GET /api/me/connections/{connectionId}/delete-impact lists them beforehand. Another member's pins keep the id, and their next run fails (pinned_connection_unavailable) until they pick again — a set never shrinks behind its owner. Another actor's enabled schedules naming the connection are disabled in the same transaction (disabled_reason: connection_deleted, jobs removed), their overrides kept: while the connection stays unreachable, re-enabling one requires a new choice. Delete-impact counts them (other_schedules_disabled_count). Surfaced only from the /connections management page — agent-surface unlinks now drop the member pin instead (see DELETE /api/me/integration-pins/{agentPackageId}/integrations/{integrationPackageId}). With a delegated or end-user credential, only connections inside its bound organization (and space, when it pins one) can be deleted (204 with no effect otherwise).
