Fix design contract findings in the research card redesign

Reuse existing radius/duration tokens where the literal value matched
one exactly, and add reviewed exceptions with a design rationale for
the bespoke pulse, shimmer, crossfade, and fold timings that have no
equivalent shared token. Renews two stale dynamic-exception hashes
whose files changed elsewhere, and adds a new one for Swap's
className forwarding, mirroring the existing ButtonRow pattern.
