docs(load-graph): classify UI and core-UX modules

Fourth classification batch: the modules that shape the first interactive frame — ui-config, ui-theme, ui-navigation, font-config, selection-framework, modeline-config, mousetrap-mode, popper-config, dashboard-config, nerd-icons-config. I annotated each header, added a Batch 4 table to the inventory, and extended the validation allowlist. 33 of 102 modules are now classified.

These mostly stay eager: each has a real first-frame reason (theme, font, modeline, completion stack, landing page). No new hidden dependencies. popper-config carries the spec's open question about its enabled/disabled state, noted for the deferral phase.
