feat(api): strip CRMEB-PRO prefix from getVersion response

The admin auth page rendered the raw version string from the .version
file (e.g. "CRMEB-PRO v3.5.1"); strip the vendor brand prefix at the
controller boundary so display matches the rebranded UI without
touching internal version detection.
