fix(iace): getProject scan missed &p.CustomerName — single-project GET 500ed

Migration 031 added customer_name to the SELECT statement in three places
(GetProject, ListProjects, ListVariants), and the per-row Scan needed the
matching destination. The replace_all caught ListProjects + ListVariants
but missed GetProject because of an indentation difference (single tab
vs row-scope indentation). Result: GET /projects/:id returned
  "get project: number of field descriptions must equal number of
   destinations, got 18 and 17"
which the frontend interpreted as "project has no data" and surfaced an
empty UI even though hazards/mitigations/components were intact (118/282/16
on Bremsscheibe).

Single-line fix: add &p.CustomerName to the GetProject scan.
