[codex] Polish inbox nested issue UI (#4959)

## Thinking Path > - Paperclip orchestrates AI agents through issue lists and issue-thread interactions > - The inbox must preserve nested issue visibility and keyboard navigation as work decomposes into deeper sub-issues > - Some UI polish issues made nested rows harder to scan and pending question cancellation less covered > - The issue list also had a small test indentation regression around load-more behavior > - This pull request tightens nested inbox rendering and related issue-thread/list polish > - The benefit is a more reliable operator inbox for multi-level work trees ## What Changed - Included nested grandchild issues in inbox keyboard navigation and recursive row rendering. - Sort parent rows by descendant activity so active subtrees remain visible. - Removed extra inbox card background styling in favor of the page surface. - Added regression coverage for pending question cancellation. - Cleaned up the issue-list load-more test indentation. ## Verification - `pnpm exec vitest run ui/src/lib/inbox.test.ts ui/src/components/IssueChatThread.test.tsx ui/src/components/IssuesList.test.tsx` - Screenshots were not captured in this PR split; the visible flow is covered by focused component/helper tests and should get browser QA in the follow-up issue. ## Risks - Medium risk: nested inbox rendering and keyboard navigation are user-visible. The changes are localized to inbox grouping/rendering helpers and covered by targeted tests. > 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 coding agent, tool use and local command execution. Exact context window was not exposed in the runtime. ## 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 - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [x] I will address all Greptile and reviewer comments before requesting merge --------- Co-authored-by: Paperclip <noreply@paperclip.ing>
