fix(ui): run paraglide compile in prepare so CI type-check finds $lib/paraglide/server

The paraglide output dir has its own .gitignore (ignores everything), so
generated files are never committed. CI ran `npm ci` then `svelte-check`
without ever invoking vite, so $lib/paraglide/server was missing at
type-check time.

Adding `paraglide-js compile` to the prepare script ensures the output is
regenerated during `npm ci` before svelte-kit sync and svelte-check run.

Also adds translation_jobs collection to pb-init-v3.sh.
