Enrichment manager modal: orb-style entrance (springy rise + cascading worker rail)

The modal opened with a plain pop — out of place next to the worker orbs. Now it
springs up from the bottom (toward the Manage Workers button) with the SAME easing
the orbs reveal with, then the worker rail assembles one-by-one: each chip springs
in staggered (scale 0.4→1) with a brief pulse of its own brand colour. Mirrors the
orb motion language AND walks your eye across every worker + its live state dot /
coverage bar as they land — cool + informative. Respects prefers-reduced-motion.
