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.
+;; Load shape: eager.
+;; Eager reason: theme persistence and the theme keybinding; the theme itself is
+;;   loaded by an explicit call in init.el.
+;; Top-level side effects: registers the custom theme load path, binds a theme key.
+;; Runtime requires: none.
+;; Direct test load: yes.
+;;
 ;; This module provides a theme management system with persistence across
 ;; Emacs sessions.
