The code centrale is LaFoir'Fouille's 11-digit product identifier
(prefix 1000x). Only products referenced by the central purchasing
office have one: ~355 800 of 427 700 articles.
The column was already synced from SQL Server and returned by the
detail route via `a.*`, but was absent from the list route and could
not be filtered on.
- list route: select artcentrale, add `artcentrale` (partial match)
and `has_artcentrale=1|0` query params
- filter matches on prefix AND length 11, so malformed values with a
valid prefix ('10000', '10000192289P') are excluded
- COALESCE in the predicate: without it, NOT (NULL LIKE '1000%') is
NULL and the 61 442 NULL rows would vanish from has_artcentrale=0
- normalise '' to null in both routes so they agree
- sync: use safeStr so empty values are stored as NULL, not ''
