Retrieves a single position by ID, returning its full details (name, type, state, location, department, description, application form configuration, salary range, custom attributes, and team/admin user lists).

If the position has a pending approval workflow, the response includes a pending_approval object describing the approvers. The org_type field distinguishes standard positions (position) from candidate pools (pool). Returns 404 if the position does not exist.

The response also includes notes: the position's public (team) notes plus the token user's own private notes, newest first, the same notes the candidate endpoints return. Other users' private notes are never returned. Each attachment url carries a key token valid for one hour. If the notes cannot be loaded, the position is still returned and notes is absent.
