Get Connection By Id

Fetch one established integration by its id, scoped to the caller's workspace, with its newest successful provider check (warnings such as a key that lacks a scope; checked_at gives its age). Read when opening a connection detail view, confirming a specific integration's configuration, or finding why part of its data does not sync. Returns the normalized record, or null when the id belongs to another tenant or does not exist - a not-found that never reveals existence.
