feat(ai-assistant): show descriptive Noz hover tooltip on all entry points

Noz launched under early access and its three entry points (header button,
floating trigger, sidebar nav item) previously showed a bare "Noz" tooltip,
which does not educate users who don't yet recognize the name. Replace it with
a shared descriptive tooltip ("Noz, your AI teammate") sourced from a single
constant so the surfaces never drift.

- Add NOZ_TOOLTIP_TITLE in components/Noz/Noz.constants.ts
- Header button and floating trigger read the constant
- Add optional tooltip field to SidebarItem; NavItem wraps the whole row in a
  Tooltip (non-pinnable items only, to avoid nesting with the pin tooltip)
- Move the trigger's Noz icon to the Button prefix slot to match the codebase
  convention for icon-only buttons
