Fix vertical alignment of Lucide icons inside Button children across
all pages by adding verticalAlign offsets (-3px for 16px icons, -2px
for 14px icons). The design system Button wraps children in an inline
span, so SVG icons defaulted to baseline alignment.
Hide the redundant top-right "Create Tenant" button on VendorTenantsPage
when no tenants exist — the EmptyState already provides that action.
Add icons to all vendor sidebar sub-items for consistency (previously
only Email Connector had one).
