Background

Introduce initialization of hints and history states in their respective schemas.

Why this is needed:

Some singleton defaults are only initialized in doGenesisSetup(...), which is not executed on restart/upgrade.
In a v0.71.2-origin deployment, History/TSS states may be absent/uninitialized when feature flags are enabled later during upgrade.
This can cause restart-time failures (e.g., History service assuming initialized state in schema restart logic).
