fc-intranet-web: bump to v202604242315wordhighlight (Lane 1γ.1)

Word-level highlighting + inline annotation popover in the
read-aloud bar, backed by TtsReader's preview-with-timings
(Lane 1δ) and the existing /api/v1/pages/{encodedUrl}/overrides
REST surface (Lane 2α).

Built from FlowerCore.Intranet.Web@9abde21 against
FlowerCore.Common@d23d4c3, both on master.
