[codex] add comprehensive UI Storybook coverage (#4132)

## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies.
> - The board UI is the main operator surface, so its component and
workflow coverage needs to stay reviewable as the product grows.
> - This branch adds Storybook as a dedicated UI reference surface for
core Paperclip screens and interaction patterns.
> - That work spans Storybook infrastructure, app-level provider wiring,
and a large fixture set that can render real control-plane states
without a live backend.
> - The branch also expands coverage across agents, budgets, issues,
chat, dialogs, navigation, projects, and data visualization so future UI
changes have a concrete visual baseline.
> - This pull request packages that Storybook work on top of the latest
`master`, excludes the lockfile from the final diff per repo policy, and
fixes one fixture contract drift caught during verification.
> - The benefit is a single reviewable PR that adds broad UI
documentation and regression-surfacing coverage without losing the
existing branch work.

## What Changed

- Added Storybook 10 wiring for the UI package, including root scripts,
UI package scripts, Storybook config, preview wrappers, Tailwind
entrypoints, and setup docs.
- Added a large fixture-backed data source for Storybook so complex
board states can render without a live server.
- Added story suites covering foundations, status language,
control-plane surfaces, overview, UX labs, agent management, budget and
finance, forms and editors, issue management, navigation and layout,
chat and comments, data visualization, dialogs and modals, and
projects/goals/workspaces.
- Adjusted several UI components for Storybook parity so dialogs, menus,
keyboard shortcuts, budget markers, markdown editing, and related
surfaces render correctly in isolation.
- Rebasing work for PR assembly: replayed the branch onto current
`master`, removed `pnpm-lock.yaml` from the final PR diff, and aligned
the dashboard fixture with the current `DashboardSummary.runActivity`
API contract.

## Verification

- `pnpm --filter @paperclipai/ui typecheck`
- `pnpm --filter @paperclipai/ui build-storybook`
- Manual diff audit after rebase: verified the PR no longer includes
`pnpm-lock.yaml` and now cleanly targets current `master`.
- Before/after UI note: before this branch there was no dedicated
Storybook surface for these Paperclip views; after this branch the local
Storybook build includes the new overview and domain story suites in
`ui/storybook-static`.

## Risks

- Large static fixture files can drift from shared types as dashboard
and UI contracts evolve; this PR already needed one fixture correction
for `runActivity`.
- Storybook bundle output includes some large chunks, so future growth
may need chunking work if build performance becomes an issue.
- Several component tweaks were made for isolated rendering parity, so
reviewers should spot-check key board surfaces against the live app
behavior.

## Model Used

- OpenAI Codex, GPT-5-based coding agent in the Paperclip harness; exact
serving model ID is not exposed in-runtime to the agent.
- Tool-assisted workflow with terminal execution, git operations, local
typecheck/build verification, and GitHub CLI PR creation.
- Context window/reasoning mode not surfaced by the harness.

## Checklist

- [x] I have included a thinking path that traces from project context
to this change
- [x] I have specified the model used (with version and capability
details)
- [x] I have checked ROADMAP.md and confirmed this PR does not duplicate
planned core work
- [x] I have run tests locally and they pass
- [x] I have added or updated tests where applicable
- [ ] If this change affects the UI, I have included before/after
screenshots

requesting merge
