Add update_notebook evals; fix prompt gaps they surfaced (#49324)

## Summary
- Add `update_notebook` eval cases (insert/replace/delete/move, a
combined delete+insert, and guard/safety cases) mirroring the existing
`create_notebook` cases, targeting the notebooks already seeded in the
mock tool harness.
- Fix two behavior gaps in `NOTEBOOKS_PROMPT`/`LIMITATIONS_PROMPT` that
these cases surfaced when run live: the assistant asking the user for a
notebook id instead of resolving it via `list_notebooks`, and the
destructive-operations warning rule not being connected to SQL written
into notebook cells.
- Soften the destructive-SQL case's `correctAnswer` to match
`update_notebook`'s real approval-gated behavior — a warning
accompanying the reported change is acceptable, not only one strictly
preceding the tool call.

## Test plan
- [x] `pnpm run typecheck` (apps/studio) — clean
- [x] `pnpm exec prettier --check` on both changed files — clean
- [x] `evals/scorer.test.ts`, `evals/transcript.test.ts`,
`evals/trace-utils.test.ts` — 21/21 pass
- [x] Ran the new eval cases live against OpenAI (bypassing the
Braintrust proxy) via Braintrust MCP; confirmed via trace inspection
that the prompt fix resolved the id-resolution gap (Tool Usage 0% → 100%
across 3 trials) and that the assistant now includes an explicit
irreversibility warning when destructive SQL is written into a notebook
cell

## Summary by CodeRabbit

- **New Features**
- Improved notebook creation and editing support across SQL, query,
chart, and time-range cells.
- Added clearer handling for saved notebooks, recurring requests, and
one-time SQL execution.
  - Enhanced validation for database cells and notebook configuration.

- **Bug Fixes**
- Improved safeguards and warnings for destructive queries, including
saved notebook queries.
  - Better handling of missing tables and notebooks.
  - More precise notebook cell updates and tool usage validation.
