Fix v0.3.7: tag dashboard + editor as dormant, generalize requires check

Functional audit found dashboard and editor render blank — they depend
on the removed sw.* imperative SDK (sw.tabs, sw.chat, sw.layout, etc).
Tagged with requires: ["legacy-sdk"] so the installer auto-sets dormant.

Generalized the dormant requires check: any unmet requirement now
triggers dormant status, not just "chat".
