Description

Brings the TableView translations from the 19 October localization update to main. The six TableView strings added in #11820 now have translations in all 85 supported languages.

Current Behavior

12 of the 19 TableView strings are translated. The cell control type ("cell"), the cell and group-header name formats, the cell text separator and the Boolean values fall back to English in every language. Coverage is 1,020 of 1,615 string-language pairs (63.2%).

New Behavior

18 of the 19 strings are translated: 1,528 of 1,615 pairs (94.6%). Two gaps remain:

TableViewCellBlankName (added in TableView: merge feature/TableView into main (#12267, #12256, #12248, #12120) #12285) has no translations yet.
The pt-PT and ug-CN translations of TableViewCellLocalizedControlType are left out because both mean "mobile phone". Those two languages keep the English "cell" until the translations are corrected.

The returned TableViewBooleanTrue and TableViewBooleanFalse values are identical to English in 13 and 14 languages, including zh-CN, zh-TW and ko-KR.

Not included from the update:

The Microsoft.Internal.WinUILocalizationResources bump to 3.0.0-experimental.261019.1, which is not on the OSS dependency feed.
MapControl placeholder files, which have no translations yet.

Customer Impact

User-facing. Screen readers announce TableView cells, cell and group-header names and Boolean values from each language's resources instead of falling back to English, apart from the gaps above.

Regression Potential

Low risk — isolated change, limited scope
Medium risk — touches shared components or public APIs
High risk — architectural or breaking API change

Resource-only: 85 non-English Resources.resw files gain entries. No code, English strings or existing translations change.

How Has This Been Tested?

I have performed a self-review of my own code
I have added tests to cover my changes
Existing tests pass locally
83 files are byte-identical to the generated update; pt-PT and ug-CN differ only by the one removed entry.
Against main: 2,032 lines added, none removed. No existing value, file header, encoding or line ending changes, and en-us is unchanged.
All 85 files parse as XML, and the format placeholders (%1!s!, {0}) match English in all 1,528 translated values.

Screenshots (if appropriate)

Not applicable.
