refactor(aggregator): simplify dependency builder

[Alenar]

Content

This PR includes a extensive splitting of the aggregator dependency builder, a 2200 lines file, in order to make it more manageable.

Main changes:

• the dependency/builder.rs is now a module with several submodules:
  • protocol: contains the core services that run the Mithril protocol (generation of signables artefacts => aggregations of signatures into a certificates => building of artefacts and generation of proofs).
  • enablers: contains the services related to sub domain cases that enables the protocol, such as communicating with the node.
  • support: contains low level services such as stores or cross-cutting concerns such as observability.

Additional change:

• some methods related to configuration access have been streamlined either by removing them and using the configuration directly or by moving said method to the configuration structure.
