Removes apps/server (Fastify, Drizzle, pg-boss, Better Auth), the
development Postgres, the backup code routes, the web HTTP client and
the CI database service. Deployment is static hosting with Caddy. A
Playwright test checks that the production build loads only its own
files.

Export save turns the whole save into one code (gzip + base64url
behind a DEADHEAD1. prefix) to copy or share as a file; Import save
takes a pasted code or a file, migrates and validates it, and replaces
the company after confirmation. A bad code is refused and changes
nothing. These replace the backup code. Debug info now gives the save
id, save version and storage type.
