Migrate vicihost.com off WordPress to Astro

Same approach as the vicidial.com migration: 58 pages, 6 posts, 41
attachments and the 4-item nav exported from wordpress_vicihost via
scripts/export-wp.mjs, with the layout and styling ported from this
site's own copy of the small-business theme.

That theme copy is not identical to vicidial's -- it carries the red
VICIhost palette, its own meta description, and shows 6 slides rather
than 5 (smallbusiness_ppp) -- so the CSS and slideshow are ported from
it rather than shared with the other site.

The export script gained handling for custom-link menu items, which this
menu uses for its "Home" entry and vicidial's did not.
