Polish board settings and skills workflow (#4863)

## Thinking Path

> - Paperclip's board UI and bundled skills are the operator layer for
configuring agents, routines, issue workflows, and local troubleshooting
loops.
> - The prior rollup mixed this operator polish with database backups,
backend reliability, thread scale, and cost/workflow primitives.
> - This pull request isolates the remaining board QoL, settings,
issue-detail integration, adapter config cleanup, and skills smoke
tooling.
> - It includes some integration-level overlap with the thread and
workflow slices so this branch can run from `origin/master` while still
preserving the full original work.
> - Preferred merge order is the narrower primitives first, then this
integration PR last.
> - The benefit is that reviewers can inspect the user-facing
board/settings/skills layer separately from backend infrastructure
changes.

## What Changed

- Added board/settings polish for agents, routines, company settings,
project workspace detail, and issue detail controls.
- Added agent/routine UI regression tests and New Issue dialog coverage.
- Integrated issue-detail activity/cost/interaction surfaces and leaf
work pause/resume controls.
- Cleaned bundled adapter UI config defaults and onboarding copy.
- Added terminal-bench loop and work-stoppage diagnosis skills plus a
smoke test script.
- Updated attachment type handling and Paperclip skill/API guidance.

## Verification

- `pnpm install --frozen-lockfile`
- `pnpm exec vitest run ui/src/pages/Agents.test.tsx
ui/src/pages/Routines.test.tsx ui/src/components/NewIssueDialog.test.tsx
ui/src/pages/IssueDetail.test.tsx
server/src/__tests__/costs-service.test.ts
server/src/__tests__/issue-thread-interaction-routes.test.ts
server/src/__tests__/issue-thread-interactions-service.test.ts`
- Result: 7 test files passed, 54 tests passed.
- `pnpm run smoke:terminal-bench-loop-skill`
- Result: JSON output included `"ok": true` and `"cleanup": true`.
- UI screenshots not included because verification is focused
component/page coverage for the changed board surfaces.

## Risks

- This is the integration-heavy PR in the split and intentionally
overlaps some component/API primitives with the issue-thread and
workflow PRs so it can run from `origin/master`.
- Preferred merge order: #4859, #4860, #4861, #4862, then this PR last.
If earlier branches merge first, this PR may need a straightforward
conflict refresh in shared UI files.
- The terminal-bench smoke script creates temporary mock issues and
relies on cleanup; the verified run returned `cleanup: true`.

> For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and
discuss it in `#dev` before opening the PR. Feature PRs that overlap
with planned core work may need to be redirected — check the roadmap
first. See `CONTRIBUTING.md`.

## Model Used

- OpenAI Codex, GPT-5.5, code execution and GitHub CLI tool use, medium
reasoning effort.
