fix(org-ui): full-width Organization pages and scrollable bodies

[XYAIStudio]

Summary

Organization submodule pages under /organization/... were a centered slim column (max-width: 880–1040px) and, with PageShell fill + overflow: hidden, could not be scrolled when content was taller than the viewport.

This PR keeps the FreeOS shell (sidebar + Organization path tabs) and makes the page body full-bleed like Chat / Knowledge / Settings, with a scrollable content region.

Follow-up: Organization Tasks discussion is now one embedded conversation pane (not a comment list plus an empty right-hand detail column).

What changed

Layout / scroll

• Shared dashboard/src/org-ui/layout/orgPage.module.css — width: 100%, no centered max-width.
• All migrated org-ui .page wrappers compose that shell.
• PageShell fill (and mobile path-tabs) now wrap children in page-shell-scroll-body (overflow-y: auto) so tall pages scroll instead of clipping.
• Organization adapters use ORG_PAGE_SHELL (fill + pathTabsPlacement="below-title") so 12 module tabs sit in two rows under the title, matching Personalization.

Tasks conversation (this follow-up)

• TaskDetailPage no longer uses a 2-column “comments list | sparse status/assignee” split.
• Left stack: task metadata, subtasks (with progress), status transition / completed state, assignee.
• Right pane (org-task-conversation): one chat-style panel — scrollable thread (avatars, bubbles, user vs comment_type=ai) + composer with Send. Empty state when there are no comments.
• Logic unchanged: still GET/POST /api/org-module/tasks/:id/comments via the injected OrgTasksClient. No FreeOS Chat runtime, no iframe.
• Composer Enter sends (Shift+Enter keeps a newline), matching a conversation composer rather than a disconnected notes list.

Visual / interaction closer to openXYOS OpenApp

• Announcements: pinned ring, hover shadow, unread pill, empty icon, Eye on read %.
• Tasks list: full-width search, status pills with counts, empty icon; row is no longer a nested <button>.
• Employees / skills / knowledge cards: hover lift; employees empty icon.
• Inner titles aligned with originals where host APIs allow (人机资源, 任务管理, 治理引擎, 反思引擎).

Standalone export

• Extra padding on [data-testid^="org-ui-"] so the same pages are usable without PageShell.

Pages touched

Adapters: workbench, workspace, announcements, org chart, employees (+ detail), skills, governance, knowledge, tasks (+ detail), reflections, settings, agents.

org-ui: shared layout + CSS/pages above. PageShell (all fill pages, including Knowledge Bases / Personalization).

Tasks-specific: dashboard/src/org-ui/pages/tasks/TaskDetailPage.tsx, TasksPage.module.css, labels.ts, TaskDetailPage.test.tsx.

Intentional remaining differences

• Ant Design tokens/controls vs original Tailwind OpenApp (buttons, tags, tables, modals).
• Org chart remains a nested department list, not the canvas / zoom / export original (html-to-image / jsPDF). Host /api/org-module/org has no layout/version/import APIs.
• Employees is the host directory (human / AI). No talent-market / reserve / offboarding tabs — those APIs are not on the host.
• Skills is generate/publish catalog wrappers, not the sidecar marketplace / plugin center.
• Governance is host PEP pauses + audit JSONL, not the sidecar permission-matrix / comm-rules / process-templates engine.
• Knowledge lists host knowledge_bases (same rows Chat uses), not sidecar notes/files folders.
• Settings edits org module toggles + local prefs; models/users/timezone stay on /system-settings.
• Chat remains FreeOS-native (not openXYOS Chat). Task discussion is host comments styled as a conversation, not a second chat runtime.
• Task attachments are not shown: host /api/org-module/tasks has no attachments API (openXYOS TaskDetail lists them).
• Task list and detail remain separate routes (/organization/tasks and /organization/tasks/:id), same as openXYOS /tasks and /tasks/:id.

Test plan

• make all after this Tasks follow-up (in progress)
• Added/updated tests

cd dashboard && npm test -- src/layouts/PageShell.test.tsx \
  src/org-ui/layout/orgPage.module.css.test.ts \
  src/org-ui/pages/**/*.test.tsx \
  src/pages/Organization/index.test.tsx

Focused Tasks vitest (8 tests) passed after the conversation merge. Browser E2E of Organization routes was not run in this environment (no running FreeOS UI). Closest substitute: unit tests + CSS contract test that .page is not a centered max-width column.

Checklist

• Updated CHANGELOG.md (if user-facing)
• README / docs updated (if needed)
