🧩 Task: Document and verify importer redesign

Automated task PR opened by Code UX for T04.

📋 Summary

Sprint: Sprint 140 · Importers - Improve UI & UX · Task: T04

Redesign the Jira, GitHub, and GitLab sprint importers into cleaner, progressive, provider-appropriate workflows that show less by default, sort and summarize results clearly, use inputs suited to each filter, preserve existing import behavior, and update focused dashboard coverage and docs.

📝 Full Task Prompt

## Objective
Bring documentation and cross-surface dashboard coverage in line with the redesigned importer UX after both provider-specific modal refactors have landed.

## Scope
- Edit `docs/dashboard/sprint-imports.md`
- Edit `docs/dashboard/dashboard-guide.md` only if its importer summary needs wording updates for the redesigned flow
- Verify `docs/index.md` and `docs/SUMMARY.md` already link `docs/dashboard/sprint-imports.md`; update them only if a new docs page is introduced, which is not expected
- Add or update cross-modal tests in `tests/dashboard/v2/components/sprints/SprintIssueImportModal.test.tsx`, `tests/dashboard/v2/components/sprints/SprintJiraImportModal.test.tsx`, or a new focused test file under `tests/dashboard/v2/components/sprints/` if shared assertions would otherwise duplicate too much setup

## Implementation Requirements
1. Update `docs/dashboard/sprint-imports.md` to describe the redesigned default importer layout, progressive advanced filters, active filter summaries, provider-specific input types, selected result summaries, and linked versus special-task import modes for GitHub, GitLab, and Jira.
2. Keep existing behavioral documentation accurate: saved tokens are still required, prompt-context imports still preserve issue bodies and optional conversations, Jira JQL still overrides guided filters, and auto-close behavior remains unchanged.
3. Add focused regression coverage that verifies both importer modals expose a low-noise default surface before advanced filters are opened and that advanced controls remain reachable and submit the same API payloads as before.
4. Add accessibility-oriented assertions where practical: dialog naming/description, keyboard-reachable close/search/import controls, `aria-pressed` or selected-state semantics for provider and issue cards, disabled import buttons with useful accessible labels, and selected-count live text.
5. Run the full focused importer test set after documentation updates to catch integration drift between shared primitives and both modal refactors.

## Constraints
- This task depends on `T02` and `T03`; do not start from the sprint branch without both redesigned modals available.
- Do not introduce a new docs page unless the implementation created a new subsystem; if a new page is created, link it from both `docs/index.md` and `docs/SUMMARY.md`.
- Do not change backend service behavior, API contracts, or sprint persistence in this documentation and regression task.
- Keep docs user-facing and accurate; do not claim visual or accessibility checks passed unless the corresponding command or test was actually run.

## Verification
- Run `pnpm exec vitest run tests/dashboard/v2/components/sprints/SprintIssueImportModal.test.tsx tests/dashboard/v2/components/sprints/SprintJiraImportModal.test.tsx tests/dashboard/v2/lib/issue-import-view-models.test.ts`.
- Run `pnpm run test:dashboard` if the focused importer tests pass and time permits.
- Run `pnpm run build` and confirm the dashboard typecheck and Vite build complete successfully.
