feat: put invite links on hold; single brand header everywhere

Invite links are dormant behind CCR_INVITES_ENABLED (default off): creation
409s, existing tokens stop redeeming with a clear message, /admin hides the
section. Pre-assigned roles remain the onboarding path; machinery and audit
history stay intact for re-enabling. Header: the CCR logo (which already
reads 'CCR') stands alone with the tagline 'Psychological Text Analysis with
Contextualized Construct Representation' - app, guide, and product topbars
now identical.
