Auto-growing name box for the new-project tile

Replace the plain <input> with a rows=1 <textarea> that grows to fit
its content on input, so a long or wrapped name stays fully visible
instead of scrolling. Enter still submits rather than adding a
newline, and the box resets to one row after a successful create.

Also make the tile's background transparent (dashed border stays) and
drop its 'Create a project' title, keeping just the Name field --
accessible label moved to aria-label since the placeholder now stands
alone.
