Add recovery handoff system notices (#5289)

## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies.
> - Agent runs can end productively while the source issue still lacks a
durable final disposition.
> - That leaves the control plane unsure whether to resume, escalate, or
close the work.
> - Issue comments also need a presentation contract so system-authored
recovery notices can render as first-class thread messages without
overloading normal comments.
> - This pull request adds successful-run handoff recovery, comment
presentation metadata, and system notice rendering.
> - The benefit is stricter task liveness with clearer operator-facing
recovery state.

## What Changed

- Added successful-run handoff decisions, wake payloads, escalation
behavior, and recovery tests.
- Added issue comment presentation metadata with migration
`0078_white_darwin.sql` and shared/server/company portability support.
- Rendered recovery/system notices in issue chat with dedicated UI
components, fixtures, tests, and storybook/lab coverage.
- Included the current recovery model-profile hint patch so automatic
recovery follow-ups use the cheap profile.

## Verification

- `pnpm install --frozen-lockfile`
- `pnpm exec vitest run
server/src/services/recovery/successful-run-handoff.test.ts
ui/src/components/SystemNotice.test.tsx
ui/src/lib/system-notice-comment.test.ts
ui/src/components/IssueChatThreadSystemNotice.test.tsx`

## Risks

- Migration-bearing PR: merge this before any other branch that might
later add a migration.
- The branch touches both recovery services and issue-thread rendering,
so review should pay attention to recovery wake idempotency and comment
metadata compatibility.

## Model Used

- OpenAI GPT-5 Codex via Paperclip `codex_local` adapter, with
shell/git/GitHub CLI tool use.
