Waleed 235f0748ca feat(files): expand file editor to support more formats, add docx/xlsx preview (#3971)
* feat(files): expand file editor to support more formats, add docx/xlsx preview

* lint

* fix(files): narrow fileData type for closure in docx/xlsx preview effects

* fix(files): address PR review — fix xlsx type, simplify error helper, tighten iframe sandbox

* add mothership read externsions

* fix(files): update upload test — js is now a supported extension

* fix(files): deduplicate code extensions, handle dotless filenames

* fix(files): lower xlsx preview row cap to 1k and type workbookRef properly

Reduces XLSX_MAX_ROWS from 10,000 to 1,000 to prevent browser sluggishness
on large spreadsheets. Types workbookRef with the proper xlsx.WorkBook
interface instead of unknown, removing the unsafe cast.

* refactor(files): extract shared DataTable, isolate client-safe constants

- Move SUPPORTED_CODE_EXTENSIONS to validation-constants.ts so client
  components no longer transitively import Node's `path` module
- Extract shared DataTable component used by both CsvPreview and
  XlsxPreview, eliminating duplicated table markup

* refactor(validation): remove Node path import, use plain string extraction

Replace `import path from 'path'` with a simple `extractExtension` helper
that does `fileName.slice(fileName.lastIndexOf('.') + 1)`. This removes
the only Node module dependency from validation.ts, making it safe to
import from client components without pulling in a Node polyfill.

Deletes the unnecessary validation-constants.ts that was introduced as
a workaround — the constants now live back in validation.ts where they
belong.
