feat: optimistic status updates

[fcsondheim]

What

• Optimistic StatusChangedEvent updates: SmartObjectProvider now applies StatusChangedEvent from the gRPC checkpoint stream immediately (before the next refetch), consistent with the existing optimistic inventory and fuel update behaviour. State is discarded if the confirmed refetch matches the last-acknowledged value (stale-refetch protection via lastConfirmedStateRef).

• BCS decoder refactor: The three event BCS files (inventoryEventBcs, fuelEventBcs, statusEventBcs) previously each had a two-step decode* + *ToParsedJson pattern with an intermediate Decoded* type that downstream consumers never used directly. Each is now a single decode*ToJson(bytes): Record<string, unknown> function. A new eventBcsRegistry.ts holds a DECODERS_BY_SUFFIX dispatch table and exposes decodeEventBcsToJson(bytes, eventType) as the single entry point. checkpointStream.ts's parseEventPayloadFromStream drops from a 3-branch if/else to a 2-liner.

Adding a new event type

Add one entry to DECODERS_BY_SUFFIX in eventBcsRegistry.ts.

Pull request overview

This PR extends the dapp-kit event pipeline to support optimistic StatusChangedEvent application (similar to existing optimistic fuel/inventory handling), and refactors event BCS decoding into a single registry-based dispatcher to simplify checkpoint stream parsing.

Changes:

• Add StatusChangedEvent BCS decoding + status event filtering/application helpers, and wire status events into SmartObjectProvider’s checkpoint-stream flow.
• Refactor inventory/fuel/status BCS decoding to a single-step decode*ToJson API and introduce eventBcsRegistry.ts for suffix-based dispatch.
• Update/add Vitest coverage for the BCS decoders (including a new status-event BCS test vector).
