fix(parser): relax detection prompt — quantities not required for social media recipes

Instagram recipes frequently list ingredients without quantities.
The old prompt required 'at least 3 ingredients WITH quantities' which
caused valid Italian social-media recipe posts to be rejected.

New criteria: dish name + 3 ingredients (any form) + 1 preparation step.
