The "which preset does this saved theme match?" loop in BrandingPage and
CreateEventPage was doing a full JSON.stringify equality on preset.config
vs the loaded theme. The previous #323 logo-preservation work means the
saved theme legitimately carries a `logoUrl` (and any other fields the
parent maintains), so the equality check would never match and the
preset summary fell back to "Custom Theme" / Classic Grid even when the
saved theme was structurally Dark Modern, etc.
Compare only on the preset's own keys instead. Surfaced by the new
smoke spec 07-branding-default-on-create-event which would otherwise
pass green against the broken state.
