Closes #4986

What changed

• Size column restored. site-config/anvil-cmg/dev/index/filesEntityConfig.ts has a sortable Size column again, placed straight after the pinned File identity column and before DRS URI. It sorts server-side on files.file_size.
• Pieces feat: reorganize anvil files index columns with consolidated identity column (#4966) #4983 removed, now back. The FILE_FILE_SIZE category key (files.file_size) and its Size label (site-config/anvil-cmg/category.ts), and the buildFileSize view builder (app/viewModelBuilders/azul/anvil-cmg/common/viewModelBuilders.tsx).
• Size chip removed. buildFileIdentity now renders only the Format and Data Modality chips, so size isn't shown twice.
• Tests. The AnVIL e2e constants (e2e/anvil/constants.ts) now include a Size column. __tests__/viewModelBuilders/file-identity.test.tsx no longer expects a size chip, and it adds buildFileSize cases: 2 kB, 0 B, and Unspecified for a missing size.

Why

#4983 moved file size into a chip in the files identity cell and removed the Size column, so the files table could no longer be sorted by size. We sort by size to find the largest and smallest files, for example when testing downloads. @NoopDog asked for this in the #4983 review, but the PR merged without it.

Assumptions I made

• Same column as before feat: reorganize anvil files index columns with consolidated identity column (#4966) #4983. It has the same id (files.file_size), header (Size), BasicCell component and width ({ max: "auto", min: "120px" }). It's visible by default, and the default sort stays on File name.
• Azul sorts by size. I confirmed the AnVIL dev API accepts sort=files.file_size (largest first: ~100 GB, ~98 GB, ~81 GB).
• Missing sizes. A file with no size shows Unspecified in the column, using getFileSize's behaviour since feat: reorganize anvil files index columns with consolidated identity column (#4966) #4983.
• Identity column width. It stays at { max: "1.5fr", min: "340px" }, unchanged even though the cell now has one chip fewer.
• Two known limits left for follow-ups, both assigned to @NoopDog:
  • fix: format file sizes of 1 pib or more and non-positive sizes in humanfilesize #4987: humanFileSize mis-formats files of 1 PiB or more, and negative or fractional sizes.
  • docs: describe anvil files.file_size in bytes in the data dictionary #4988: the AnVIL data dictionary says files.file_size is in megabytes, but it's bytes.

How to verify

1. Run npm run dev:anvil-cmg (or open this branch's AnVIL dev deployment) and go to the Files tab.
2. Check the Size column appears right after the File column, before DRS URI.
3. Click the Size header. Files sort by size, and clicking again reverses the order (largest first shows files of ~100 GB).
4. Check the File identity cells show only Format and Data Modality chips, with no size chip.
5. Run npx jest __tests__/viewModelBuilders/file-identity.test.tsx. All tests pass.
6. Optional: run npm run test:anvil-cmg -- --project chromium. The Files tab sort and column tests pass with the Size column.

Definition of done from #4986:

• Size is its own sortable column, placed first after the File identity column → steps 2 and 3
• buildFileSize and the FILE_FILE_SIZE category key and label are restored → steps 3 and 5
• The size chip is removed from buildFileIdentity; Format and Data Modality stay as chips → steps 4 and 5
• The AnVIL e2e column constants and the buildFileIdentity unit tests are updated → steps 5 and 6
