Handoff page for bulk label printing when the user prints over Bluetooth inside the app.

Rendered by LotLabelView.get() instead of the PDF, so every bulk entry point -- the users-table
links, ?printredirect=, the command palette, a bookmarked URL, print-after-bulk-add -- goes to the
printer rather than handing a thermal-printer user a letter-size PDF sheet they can't feed.

It navigates rather than 302s: a synthesized <a> click is the path the app is known to intercept
today (it is how the per-lot fishauctions://print/<pk> link already reaches it), and a redirect to a
custom scheme is not. The manual button below is the fallback if the automatic click is blocked, and
also the whole page on the web, where the scheme has no handler at all.

    Bluetooth printing needs the FishAuctions app. To print a PDF instead, change
