Drop two more unneeded width caps

- .tabs__panel--narrow (42rem, the project view's 'All tasks' tab):
  removed the class and its rule, same reasoning as the config
  sections -- the page around it is already full-width.
- Profile now sets meta.wide, so it uses .app__main--wide instead of
  the default .app__main's 32rem cap, matching the dashboard/project/
  configure views instead of sitting narrow like the login form.
