fix(web): room for the title in the new ticket form

A field's label floats above its box and only other fields leave room
for it, so «Título» sat on the type selector. Also: the mention hint
had the shell's paragraph size instead of a hint's, and «Asignar a» and
«Release» offered «Todas las personas» / «Todas las releases», filter
words, for «nobody» and «none».
