Bug #3 (HIGH): New habit button on /habits did not open the create
dialog. The HabitCreateDialog was mounted but the topbar's
useCreateDialogStore had no consumer on /habits, so topbar clicks
were no-ops.
Bug #4 (HIGH): New project button on /projects had the same issue.
Fix: mount CreateItemDialog (type=habit or type=project) on each
page so the topbar store is consumed. Switch the page-level button
to use the store too. The existing local HabitCreateDialog /
ProjectCreateDialog still work as a fallback.
Bug #5 (HIGH): Domain Add button on /settings/domains opened the
Command Palette instead of creating the domain. Two-part cause:
1. The sticky topbar Quick add button was visually overlapping
the form Add button (both anchored top-right). On click the
topbar handleCreate fired and dispatched a synthetic Cmd+K
opening the palette.
2. /api/domains POST required a slug field that the form did not
send, returning 400.
Fix: hide the topbar Quick add button on pages without a relevant
quick-create (only show on /projects, /habits, /tasks). Make the
form Add button explicit type=button with stopPropagation as
defense in depth. Auto-generate the domain slug from the name
on the server when not provided.
Bug #3 + Bug #4 + Bug #5 all fixed in this commit.
