DottaandPaperclip 9b3fe260ba fix(tasks): surface Codex ChatGPT model rejection (#15299)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for work.
> - Native Runner runs report provider errors and can also save a structured failure result.
> - Codex rejects a model that the user's ChatGPT account cannot use.
> - Master now diagnoses this rejection, but the task's compact run data omits its message. The thread can still call it a generic run failure.
> - Users need the account restriction and a clear step to repair the model selection.
> - This pull request shows the existing diagnosis as “Model unavailable” on the task.

## Linked Issues or Issue Description

**What happened?**

Codex returns HTTP 400 with `invalid_request_error` and the message `The 'gpt-6.1-sol' model is not supported when using Codex with a ChatGPT account.` Master now stores an actionable diagnosis for this rejection. The task thread still labels it “Run failed” and does not receive its error text in compact run data.

**Expected behavior**

Show the account restriction on the task and in the run error. Tell the user to choose a supported model or clear the task's model override before retrying.

**Steps to reproduce**

1. Use a Native Runner Codex agent signed in with a ChatGPT account.
2. Select a model that produces the rejection above and start a task.
3. Let the runner save its generic failed result. Inspect the task's failure marker and recovery notice.

**Additional context**

Refs: #15304. That merged PR diagnoses the provider failure and preserves worker and review recovery rules. This PR adds its task-facing message and guidance without changing that diagnosis or those rules.

Refs: #13134. That PR improves model discovery for ChatGPT accounts. This PR exposes the rejection when a configured model still fails at execution time.

## What Changed

- Return a bounded model rejection message in compact issue-run data.
- Show “Model unavailable” and model-change guidance in the task thread and recovery notice.
- Add database and UI regression tests, including both the original rejection text and master's fixed diagnosis. Document the new failure message.

## Verification

- Focused merged-branch validation: 279 tests passed across activity service, native provider failure observation and PostgreSQL integration, TaskChatThread, and ExecutionBlockerNotice.
- `pnpm -r typecheck`, `pnpm build`, and `pnpm check:token-gates` passed on the merged source tree.
- Greptile reviewed conflict-resolution commit `1db39c4e636a92e2e76ba224b71c6f1e2f556c81` at 5/5 with no findings or inline comments.
- All 55 check runs completed without failure on that commit. The two optional Storybook jobs were skipped. The legacy Snyk status passed. The branch has no merge conflicts.
- UI regression assertion: the task's failure marker says “Model unavailable” and retains the account restriction. It no longer says that this failure happened after a final response.

## Risks

- Provider recognition and recovery are owned by the existing master implementation. This PR exposes only bounded error text for failed runs with `native_provider_model_rejected`.
- Historical runs with the generic `adapter_failed` code are not reclassified. No stored run is rewritten.
- Existing retry and reconciliation gates remain in place. No schema migration or model configuration change is required.

## Model Used

OpenAI Codex, based on GPT-6, with reasoning, code execution, and browser inspection. The exact deployment model ID and context window are not exposed in this session.

/**
* Chat-style task thread — the default task detail experience.
*
* Renders the Claude-Code-style thread for the live task. It shares
* IssueChatThread's exact prop type — so the IssueDetail seam ternary
* (`classic ? IssueChatThread : TaskChatThread`, flag:
* `enableClassicTaskInterface`) type-checks with no casts.
*
* Two data sources feed the render layer, both reused from the existing thread:
* - the comment stream (incl. optimistic echoes) → author-typed bubbles, and
* - the live run transcript (useLiveRunTranscripts, the same poll+websocket
* source the current thread uses) → clean TaskChatLiveTail rows (tool cards,
* diffs, streamed reply markdown) while in flight, via the same
* transcriptToTaskChatItems converter the settled turns use (PAP-463).
*
* Once a run terminates, its settled turn anchors after the run's
* last comment (comment.runId linkage) and — when it directly follows that
* reply bubble — attaches to it: the "✓ Worked · …" summary renders appended
* to the bubble's always-visible timestamp line (round 9), still expandable
* to the tool history. Turns without a reply bubble keep the standalone
* folded row. flag-OFF remains byte-for-byte IssueChatThread.
