keep.kidlisp.com: fix rekeep flow end-to-end
- lith/Caddyfile: dedupe Access-Control-Allow-Origin on ipfs.aesthetic.computer
so browsers stop rejecting the gateway with "*, *". Kubo already emits the
header; strip upstream copies and let Caddy own exactly one.
- keep-update.mjs: drop Pinata (403s) in favor of self-hosted Kubo with oven
seeder mirroring, matching keep-prepare-background.mjs.
- keeps.html: await initAuth0 in startMintFlow before deciding on the Bearer
header, fixing the first-click race that produced a spurious 401 on the
validate-ownership step.
