P1 Badge Preserve retrievable image URL in qron_generations

When the worker returns a data URI, this stores image_url as generated:${qronId}, but there is no code path that resolves generated:* back to an actual image URL, while /api/qron/[id] returns qron.image_url directly (app/api/qron/[id]/route.ts, GET response). That means QRONs generated through /api/generate lose a renderable/downloadable image reference once reloaded from the database, so downstream consumers of persisted records receive a non-URL placeholder instead of an image.

Useful? React with 馃憤聽/ 馃憥.

await admin.from('qron_generations').insert({
id: qronId,
user_id: session.user.id,
image_url: imageUrl,
image_url: storableImageUrl,
