## PR-Codex overview
This PR focuses on enhancing the event stream monitoring capabilities by
introducing new types and methods to track block events, including event
counts by type, and updating the related structures across multiple
packages.
### Detailed summary
- Introduced `eventCountsByType` in `BlockConfirmedBody`.
- Added `BlockConfirmedBody_EventCountsByTypeEntry` interface.
- Modified `createBaseBlockConfirmedBody` to initialize
`eventCountsByType`.
- Updated serialization and deserialization logic for
`BlockConfirmedBody` to handle `eventCountsByType`.
- Created `EventStreamMonitor` class to manage event counts and monitor
block events.
- Integrated `EventStreamMonitor` into `HubEventStreamConsumer`.
- Enhanced error handling and logging for missed events and old events
in the event stream.

## Why is this change needed?
This eliminates the need to keep 2 sets of protos in sync with one
another. Generated files should be backwards compatible because we've
kept the protos in sync so far.
Some material updates
- Snapchain doesn't have the bulk streaming rpcs we used for
reconciliation in hubs. Deleted all the shuttle code that depends on
these rpcs
- In the Snapchain protos, admin rpcs are specified in a different
proto. This caused some small amount of churn.
- The admin rpcs in snapchain do not mirror the admin rpcs on hubs.

## PR-Codex overview
This PR focuses on removing outdated `.proto` files and updating the
generation of client libraries from new `snapchain` protobufs. It also
introduces type guards for the `BlockConfirmed` event and modifies
various message structures in the codebase.
### Detailed summary
- Deleted outdated `.proto` files in `protobufs/schemas`.
- Updated `package.json` scripts to generate clients from `snapchain`
instead of local schemas.
- Added type guards for `BlockConfirmed` events in `typeguards.ts`.
- Modified message structures to include `BlockConfirmedBody`.
- Updated comments for clarity in `message.ts`.
- Refactored `MessageReconciliation` class to remove streaming logic.
- Introduced new methods for handling on-chain events in `admin_rpc.ts`.
