bread-utils: expose xdg::home_dir(); document two more tilde-fallback bug sites

Browse source 
home_dir() was already computed internally (home_or_root) but not exposed
— breadarr-shared's own expand_home() helper needs it to fix the same bug
class documented in this module: its own fallback (when HOME itself isn't
set) returned the literal unexpanded "~/..." input string instead of a
real path. Also documented breadmon/src/profile.rs's profiles_dir(),
fixed in that repo's own commit.
