Release the ENCODE Expression tracks for mm10 and mm39. refs #37001

Drop the alpha,beta release tags from all three include lines, so the container
and the bigWig signal composite now ship to beta and public. Verified with
tdbQuery -strict at all three release levels: no errors, and the tracks are
visible at each one (320 on mm10, 3 on mm39).

Point the pennantIcon at the news archive post and give it the release date:
newsarch.html#090426 "Released Sep. 4, 2026", matching the convention used by
the other released tracks. The liftOver pennants on the mm39 subtracks are
unchanged.

Add the Sep. 4 news announcement to newsarch.html and a matching entry to
indexNews.html, dropping the oldest front-page item to stay at the six-item
limit. The announcement links to the session at
genome.ucsc.edu/s/Lou/ENCODEexpression and includes a screenshot of Gap43,
whose expression rises through development and is highest in the four neural
tissues.

Add the screenshot image, which was previously untracked.
