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.

+;; Layer: 2 (Core UX).
+;; Category: C/P.
+;; Load shape: eager.
+;; Eager reason: window-navigation keybindings and winner/buffer-move setup for
+;;   the first session.
+;; Top-level side effects: defines a navigation keymap, binds five global keys,
+;;   configures packages via use-package.
+;; Runtime requires: none (configures packages via use-package).
+;; Direct test load: yes.
