Adds Postgres as an alternative persistence backend for ateapi as
proposed in #731. Currently this is opt-in with flags in ateapi or use
the `--store-backend=postgres` option in the install script.

Benchmarks are not included in this PR, but you can reproduce the
results by following the doc above
Limitations and questions:
- This draft does not yet handle migrations, this might come as a follow
up
- It currently uses `testcontainers` for testing Postgres, but as a
result it adds a lot of dependencies

## Summary
Bumps `github.com/google/go-containerregistry` v0.21.5 → v0.21.7. Phase
0 of #463.
v0.21.6 fixed the memory spike in `mutate.Extract` described in #120
(upstream fix: google/go-containerregistry#2190, merged as
google/go-containerregistry@38d6e4087c): extraction is now refactored
into a per-layer `extractLayer` function, so each layer's decompressor
and HTTP response body are closed as soon as that layer is processed,
instead of all being held open via deferred `Close` calls until the
entire (multi-GB) extraction completes. atelet's pull path goes through
`memorypullcache.Fetch` → `mutate.Extract`, so this directly caps its
extract-time memory.
Note this is only interim relief: #437's unbounded cache retention is
untouched and is addressed by the redesign in #463.
## Changes
- `go-containerregistry` v0.21.5 → v0.21.7, plus required transitive
bumps: `docker/cli`, `klauspost/compress`, `golang.org/x/sync`,
`golang.org/x/sys`
- `go mod tidy` + `go mod vendor`; the
`containerd/stargz-snapshotter/estargz` vendor tree drops out (upstream
removed the estargz integration; nothing in substrate used it), along
with `vbatts/tar-split` and `mitchellh/go-homedir`
## Testing
- `go build ./...` passes
- Full `go test ./...` passes
- Verified the layer-close fix is present in the vendored
`pkg/v1/mutate/mutate.go`
