Clicks `+ new file` at the overlay root, fills the routed editor's
filename + CM6 content, and clicks Create. Asserts the modal closes,
the file lands on disk, AND the new row appears in the live tree
after the debounced HTMX refresh — the last assertion catches the
class of bug where /files/save persists but
scheduleRefresh(parentOf(fullPath)) never lands a fresh listing.
The new-file modal reuses overlay_file_editor.html with is_new=True;
this test exercises the branch in routedSaveClicked that composes
fullPath from filename + data-at-folder, distinct from the
rename-on-save path the edit-mode test covers.

Opens server.cfg through the file-row name button, drives the CM6
controller via window.__filesEditor.setContent, clicks save, and
asserts both that the routed modal closes and that the new bytes
landed on disk under overlay_root. Guards against four classes of
regression at once: the /files/edit fragment delivering the wrong
data-rel-path, editor.js's htmx:afterSwap re-init failing to wire
__filesEditor, routedSaveClicked stopping short of closeRouted(),
and the /files/save endpoint failing to persist.
Adds a `_wait_for_routed_editor` helper centered on `.cm-content`
inside `#files-editor-fragment` — the textarea itself is
display:none after CM6 mounts, so to_be_visible on the textarea
would always fail; the cm-content surface is the real "editor is
ready" signal.
