fix(project): the goal field is a textarea, not a one-line input

A project goal is a paragraph in practice. This one rendered as "Maintain
Scribe as the reliabl" with no way to read the rest but arrowing through it,
in a sidebar with room to spare. Description gets two more rows for the same
reason.
