feat(web): add memory button to company brain navbar

The company brain header had no Add button (only Invite + Search). Wire
the onAddMemory callback through Header into CompanyBrainHeader and add an
Add button to the desktop action cluster plus an "Add memory" item at the
top of the mobile hamburger menu, matching the personal header pattern.
