feat(procurement): allow re-tendering after the 3-offer gate rejects a tender

When fewer than three offers pass technical evaluation the tender is
flagged "تحتاج إعادة طرح" — but that status also hid the invite-vendors
form, so there was no way to actually invite more vendors and the
process dead-ended with no route forward.

Adds a "إعادة طرح المناقصة" action next to the rejection reason that
returns the tender to published and clears the reason, so additional
vendors can be invited and their offers recorded.
