chore(update): point post-update banner at apl-feed status (#92)

* chore(update): point post-update banner at apl-feed status

The post-update banner instructed users to confirm feeding by running netstat against a hardcoded production IP. That IP is wrong for anyone running custom infra, and the advice predates apl-feed status, which now covers link + website ingest + claim + diagnostics in one command.

Also drop a stray trailing space in the test_apl_feed_cli.bats ss stub for consistency with the sibling stubs in test_apl_feed_status.bats.

* chore(update): swap /myfeed/ pointer for feeder claim CTA

The /myfeed/ page only works when browsed from the feeder's public IP. The apl-feed status line shown one block above already covers the same check and works from anywhere. Drop the redundant pointer and replace it with a CTA to claim the feeder on airplanes.live, which gives logged-in users full statistics and acts as a sign-up prompt for users without an account.

URL is derived from APL_FEED_WEBSITE_URL with airplanes.live as the default, so custom-backend feeders get the right host.
