Config: allow (gitea|processor).${KITSPACE_DOMAIN} for next images

- Add `gitea.${KITSPACE_DOMAIN}, and `processor.${KITSAPCE_DOMAIN} for
  nextjs image optimization allowed domains.
	- There is no wildcards support yet, see vercel/next.js#27345
- Remove ISR environment variables as they are no longer used.
