fix(test): bump Docker test timeout to 60s

The 3 'DynamoDB Local (Docker)' tests pass locally but time out at
5001ms in CI because GitHub-hosted runners have to pull the
`amazon/dynamodb-local` image on first use (often 30-60s) before
the container can even start. Bun's default 5s timeout is nowhere
near enough.

The `dockerAvailable` early-return guards are kept — they catch
environments where docker isn't installed at all. The new timeout
covers the case where docker IS available but image pull + container
start exceeds 5s.
