Rename .title CSS class to .page-title to avoid libadwaita collision

bread-theme's shared .title rule (1.4em bold) was a bare class selector
that also matched libadwaita's internal row/window-title labels, which
carry the same "title" class. That's what inflated breadman's settings
row titles to ~24px. Scoping the name to .page-title here (the only
consumer of the old class) and bumping bread-theme to the dev branch
where the rename lives.
