Three bugs:
1. +page.server.ts returned an unawaited Promise — SvelteKit awaits it on
the server anyway so data.jobs arrived as a plain AIJob[] on the client,
not a Promise. The $effect calling .then() on an array silently failed,
leaving jobs=[] and the table empty. Fixed by awaiting in the load fn.
2. +page.svelte $effect updated to assign data.jobs directly (plain array)
instead of calling .then() on it.
3. handlers_textgen.go: final UpdateAIJob (payload+status write) used
r.Context() which is cancelled when the SSE client disconnects. If the
browser navigated away mid-job, results were silently dropped and the
payload stayed as the initial {pattern} stub with no results array.
Fixed by using context.Background() for the final write, matching the
pattern already used in handlers_image.go.
