New "This app might stop working soon" banner in all our UIs

They’re all over the place on communicating that:

  • “begins Q4 CY2026” [1]
  • “at the end of 2026” [1]
  • “in December 2026” [1] [2]
  • “until December 2026” [1]
  • “December 31, 2026” [1]

Need a precise date for EOS and another precise date for EOL.

And realistic timelines without the usual silly games we’ve all come to painfully know.
