Refactor timepoint retrieval & conversion to signed entities

[Alenar]

Content

Following changes introduced in #1727 the conversion of time points to signed entities became more cumbersome. Instead of only using a CardanoNetwork it also needed now the newly introduced CardanoTransactionsSigningConfig.

This PR make this easier by delegating the configuration to a new in memory type: SignedEntityConfig, that is created at configuration time and is in the application dependency container.

This type also takes responsibility, previously in the aggregator Configuration, to list allowed signed entity types from a time point. It also hold statically the list of default types that should always be allowed.

Also in this PR: Rename TimePointProvider to TickerService and remove the conflicting service, named the same, from the aggregator.
Those two were doing the same things and comments were in the code to remove the TimePointProvider in favor of the TickerService, but the former continued to evolved even if the later api & naming were preferred. So this PR fixes this contradiction by "fusing" them together.
