/**
 * Persistence for the annual-report compliance profile.
 *
 * Error contract: Supabase errors are rethrown untouched, exactly as
 * `lib/articles/validate-revenue-account.ts` does. Re-wrapping them in a plain
 * `new Error(...)` kept only `.message` and dropped `.code`, so `errorResponse()`
 * could no longer see the SQLSTATE and mapped every constraint failure on this
 * table to INTERNAL_ERROR / 500. The reachable ones are real caller mistakes:
 * 23514 from `annual_report_profiles_parent_consistency` (e.g. setting
 * `parent_group_size` on a row already stored with `is_parent_company = false`,
 * since the upsert only writes the columns present in the payload) and 42501
 * when RLS refuses the write. With the code intact those become 400/403 with a
 * Swedish message. SQLSTATEs that are genuine infrastructure trouble are not in
 * `postgresCodeToStructured()` and still fall through to 500.
