feat(menu): priority-sorted menu groups, user-menu items, sidebar appearance toggle

Every main_menu entry moves from numeric group (1/2/3) to string-based group + group_label + priority. Groups now carry their own i18n label and child entries are sorted by an explicit priority field instead of config-array order, so module-contributed menu items can slot into any existing group at any position.

BootstrapController merges module-registered menu items into main_menu (previously they lived in a separate module_menu response key) and introduces a user_menu response key for items modules want to place in the avatar dropdown. The global store follows suit: moduleMenu becomes userMenu, menuGroups is a computed that sorts by priority, and hasActiveModules drops out.

New admin Appearance setting page with a single toggle for whether sidebar group labels render — so instances that prefer a compact sidebar can hide the Documents/Administration/Modules headings without losing the grouping itself. CompanyLayout watches route meta and re-bootstraps when the admin-mode flag flips so the sidebar repaints with the right menu on navigation across the admin boundary.

Test suites updated: module menu merging is asserted against main_menu (name: 'module-{slug}') rather than the old module_menu response; HelloWorldIntegrationTest verifies the schema translation path; CompanyModulesIndexTest covers the display_name attachment.
