store: Do not crash the node on invalid StoreEvent

It is possible to receive invalid store events when a node is starting up
because Postgres still has events sent by a previous version of the
code. In that case, the best we can do is ignore these events.

Once we've seen enough valid events, go back to panicing on invalid events.

store: Remove metadata printers from layout helper

Some of the printers in the layout helper were only there to generate
queries for metadata. That's not necessary anymore, and the metadata schema
is no longer compatible with how we generate DDL from GraphQL schemas

graphql: Add `subgraphError` argument only when feature is present

We saw an issue in a graphql client that is avoided by doing this.
and it is generally more correct to only include it if the subgraph opts in.
This requires storing the `features` field in the metadata, which we should be doing anyways.
