fix(seafarer): route registration through the application wizard

/seafarer-registration had a page of its own that wrote the profile directly
and created no application at all. A "submitted" registration was therefore
never reviewed, never approved and never numbered — there was nothing for an
officer to open. The shared wizard, the review queue and the approval side
effects all already existed; only the route pointed away from them.

The page is deleted rather than repaired. It was a second wizard maintained
alongside the config-driven one, and the seed already describes every step it
was hand-rolling — including the physical characteristics and medical details
added this release, which it would not have known about. /seafarer-registration
now redirects, so navigation, deep links and the profile gate keep working.

Also adds Configuration -> Number Formats, for the shape of generated seafarer,
seaman book and BTC numbers. The sample is rendered by the server rather than
formatted here, so the preview cannot drift from what an approval will actually
generate, and asking for one never consumes a number.
