bug(cdk/table): CdkTable does not handle column updates correctly when using recycleRows

### Is this a regression?

- [ ] Yes, this behavior used to work in the previous version

### The previous version in which this bug was not present was

_No response_

### Description

When using `CdkTable` with the table `recycleRows` directive it doesn't look like the table doesn't re-render cached rows not currently in the DOM. This leads to a situation where if those cached rows are later re-used the cells in the row don't match the columns.

It seems like this may be just a matter of clearing the row cache in `_forceRenderDataRows`. This assumes the row elements can't be re-used at all, but that seems to be the current behavior of `_forceRenderDataRows` to re-render everything. It looks like this could be achieved by calling `detach` on the `_RecycleViewRepeaterStrategy` instance in `_forceRenderDataRows`, but it's unclear the semantics of that method since it's not documented in `_ViewRepeater`. `CdkVirtualForOf` only calls it in `ngOnDestroy` and **`CdkTable` never calls it** (probably a separate bug where these row views get leaked when the table gets destroyed).

### Reproduction

StackBlitz link: https://stackblitz.com/edit/mssn6jgh?file=src%2Fexample%2Fcdk-table-recycle-rows-example.ts
Steps to reproduce:
1. Click `Set Short List` to reduce the number of rows to 15 (caching the 10 removed rows).
2. Then click `Toggle Columns`. This forces a full re-render through `_forceRenderDataRows` (which doesn't populate the cache when removing).

### Expected Behavior

All 15 rows re-render correctly

### Actual Behavior

When the 15 rows are re-rendered 5 have the old list of 3 columns since they were inserted from the cache and the remaining 10 are new rows and render correctly.

### Environment

- Angular: 20.2.4
- CDK/Material: 20.2.4
- Browser(s): 141.0.7390.126
- Operating System (e.g. Windows, macOS, Ubuntu): ChromeOS

src/example/cdk-table-recycle-rows-example.ts の StackBlitz の例で問題を再現し、その後 CdkTable._forceRenderDataRows と _RecycleViewRepeaterStrategy の detach 動作を調査します。リストを減らした後に列を切り替えると、キャッシュから再利用された行を含め、対応する列を持つ 15 行すべてがレンダリングされることを確認します。
