Léo 1323fab0bd refactor(tests): read the whole cascade instead of style.css alone
static/style.css no longer holds every rule. 79 rules for the document,
gallery and editor panels now live in static/css/, yet 27 browser tests still
built their synthetic page with a single <link> to style.css, and 51 more read
that one file as though it were the whole cascade. Those tests kept passing
while covering less: a rule that moved became invisible to the assertion that
was meant to pin it.

Python readers now call tests.helpers.stylesheets.app_css(), and synthetic
pages are built from stylesheet_link_tags() so they load exactly what
index.html loads, in the same order. The helper already existed; this moves
the remaining callers onto it.

test_portal_dropdown_z_js parametrised over a file list including style.css to
assert an absence. Checking a negative against one file of a split stylesheet
is how a moved rule escapes, so the CSS case now checks the concatenation.

Two guards keep it from coming back: one fails on any test reading
static/style.css directly, the other on any synthetic page linking it alone.
Both name the helper to use.

No production code changes. Suite is unchanged at 6 pre-existing failures.

"""Regression guards for the Documents editor scrolling UI.
Issues #1501 and #1496 both come from the same surface: the document editor
hid its real textarea scrollbar, and the line-number gutter tried to scroll an
overflow-hidden element. Long wrapped lines add another wrinkle: the textarea
can have more visual rows than logical newline rows, so the gutter rows must
match the textarea's measured row heights. Keep these as static checks because
document.js is browser-coupled and not importable in pytest.
