fix(project): reject empty/whitespace-only --name in create and update

project create/update validated --name with the action handler's if (!name) check, which a whitespace-only string passes (a non-empty string is truthy). The blank name was then sent verbatim, creating a junk-named project. The sibling 	est create already rejects this via the requireString whitespace guard (dogfood P1 fix #1); this aligns project create/update with that behavior. Adds 2 regression tests.
