feat(core-shared): add AnalyticsProtocol to BindContext and BindProductionContext

Adds analytics?: Analytics generic field to both BindContext and
BindProductionContext in bind-context.ts, mirroring the pattern used by
IEventBus, IAuditLog, and IJobQueue. AnalyticsProtocol already existed
in bind-protocols.ts and is re-exported from the @repo/core-shared/di
barrel via the existing wildcard export.

Also adds a type-level test for AnalyticsProtocol in bind-protocols.test.ts
to match test coverage for the other protocol types.
