fix(mobile): restore main's guard conditions on the four Project-row actions

Each had gained a non-null target requirement that demanded a number and a
recognised item type where main's guard did not, so a row main would have sent
for now returns silently or reports an error.

File-viewed and the comment reply gate on main's conditions and build the
never-null identity target after them. Metadata update, issue type and comment
add gate on the slug and the number, as main did, through the slug target,
which does not read the item type.
