test(web): refresh web aria goldens stale on master

These 15 goldens already failed replay at origin/master d17fcd3a6 before this
branch touched anything: master's committed expectations lag master's own code
(localized sidebar labels, the access-mode control becoming a button, message
IconActions and clock placement, context-injection affordances).

Recorded by running DSH_SNAPSHOT=refresh over the web suite in a pristine
worktree at that commit, then importing the result here, so the stats-line
change in the following commit shows up as its own reviewable delta rather than
mixed into pre-existing drift.

Two web e2e specs still fail at that same pristine commit for non-golden
reasons and are untouched here: queue-actions (counts 2 user/message events
where it expects 1) and details-session-lifecycle (times out waiting for a
New session button).
