test(frontend): cover ListItemComponent edit helpers and FilesUploaderComponent conflict prompts

[mengw15]

What changes were proposed in this PR?

Extends two dashboard component specs to cover their remaining untested
edit/interaction methods (Vitest; no production code changed).

ListItemComponent (+5 tests) — setEditingState (toggles the name /
description edit flags), renderMarkdownPreview (strips markdown syntax and
collapses whitespace), and updateProperty (missing-id guard, success
persistence + exit-edit-mode, and error revert + notify).

Note: the other ListItem methods the issue lists (onEditName /
onEditDescription / toggleLike / onCheckboxChange / openDetailModal /
initializeEntry / confirmUpdate*) are already covered on main (added in
#6557), so this PR only fills the remaining gaps.

FilesUploaderComponent (+4 tests) — markForceRestart (flags the item),
getOwnerAndName (returns the owner/name inputs), and askResumeOrSkip /
askUploadOrSkip (resolve with the clicked conflict-modal footer action). The
modal is driven through the spec's existing capturing double.

Closes #6749

How was this PR tested?

Extended unit tests, run locally in frontend/ (all green; each spec's failure
path was verified by breaking an assertion to confirm it goes red):

ng test --watch=false --include src/app/dashboard/component/user/list-item/list-item.component.spec.ts        # 25 passed
ng test --watch=false --include src/app/dashboard/component/user/files-uploader/files-uploader.component.spec.ts # 12 passed
prettier --write <specs>   # clean
eslint  <specs>            # clean
