Fix seeder: origin mismatch + robust Dockerfile

Two root causes for seeding not working on production:

1. Origin mismatch: The seeder writes content IDs as
   http://localhost:7777/content/... but the app was using
   window.location.origin (the user's actual browser URL) to
   query the relay. Introduced VITE_CONTENT_ORIGIN env var
   baked into the Docker build so both sides use the same origin.

2. Dockerfile.seed fragility: Replaced --omit=dev + global tsx
   with a cleaner approach that strips sharp from package.json
   (the only native dep that fails on Alpine) then does a full
   npm install, ensuring tsx/esbuild and all applesauce deps
   resolve correctly.

Also improved wait-for-relay to accept any HTTP response (some
relays return 4xx for plain GET) and increased max attempts.
