egg 35d83d424c feat(shell): fluid layout with collapsible sidebar drawer + fix query-tool MultiSelect

Convert portal shell from block-centered (max-width 1600px) layout to full-viewport
fluid flexbox with collapsible sidebar: desktop push-mode (240px → 0), mobile overlay
drawer with backdrop. Rename .content → .shell-content to avoid CSS collision with
page-level classes. Override page-level max-width constraints when embedded in shell.

Also replace native <select multiple> in query-tool with shared MultiSelect component
for equipment and workcenter group filters, matching resource-status/history UX.

Why

The portal shell just completed an iframe-to-Vue migration but still uses a block/card-based layout with max-width: 1600px centered shell, fixed 220px sidebar, and rounded-corner card containers. This creates a segmented "boxed" appearance with wasted screen real estate and occasional card overflow issues. Converting to a full-screen fluid layout with a collapsible sidebar drawer maximizes usable space and provides a modern dashboard experience.

Scope: This change is Portal Shell Modernize Phase 1 — it targets the shell layout layer only (header, sidebar, content wrapper). Page-level component redesign (cards, tables, charts within individual pages) is out of scope and should be addressed in a separate Phase 2 change.

What Changes

BREAKING: Remove max-width constraints from the portal shell (.shell 1600px) and all page-level wrappers (.dashboard 1800px, .qc-gate-page 1900px, .job-query-page 1680px, etc.) — content fills available viewport width
Remove border-radius and border from the shell header, sidebar, and content area — edge-to-edge fluid appearance
Convert .shell-main from CSS Grid (220px | 1fr) to Flexbox with animated sidebar width transitions
Add collapsible sidebar: desktop push-mode (width animates from 240px to 0), mobile overlay-mode (slide-in drawer with backdrop)
Add hamburger toggle button in the shell header
Add sidebar state persistence via sessionStorage
Add mobile overlay backdrop with fade transition
Add keyboard accessibility (Escape to close mobile drawer)
Maintain existing gradient color scheme, navigation hierarchy, card-level styling within pages

Capabilities

New Capabilities

collapsible-sidebar-drawer: Sidebar collapse/expand behavior, toggle button, mobile overlay, state persistence, keyboard accessibility, smooth transitions

Modified Capabilities

spa-shell-navigation: Shell layout changes from block-centered grid to full-screen fluid flexbox; sidebar becomes collapsible; content area becomes scrollable flex child
tailwind-design-system: CSS variables updated (--portal-shell-max-width removed), .u-content-shell utility changed from max-width to full-width

Impact

Portal shell (frontend/src/portal-shell/App.vue, frontend/src/portal-shell/style.css): Major layout restructure — template adds toggle button, overlay, class bindings; CSS rewrites .shell, .shell-main, .sidebar; .content renamed to .shell-content to avoid class collision with page-level .content (e.g. in tables module)
Global styles (frontend/src/styles/tailwind.css): CSS variable updates, utility class changes
Shell-registered page modules only: Page-level max-width and padding overridden when embedded in shell via .shell-content .xxx-page selectors (standalone rendering unaffected). Verification scope limited to pages registered in shell route contracts — unregistered routes (e.g. missing contract warnings) are excluded
Health popup: z-index adjustment needed to stay above new sidebar overlay layer
No new dependencies: Pure Vue + Tailwind + CSS, no additional libraries
New test file: frontend/tests/portal-shell-sidebar.test.js — automated tests (Node node:test harness) for sidebar collapse/expand, mobile overlay, and sessionStorage persistence
