feat: aggregation mode explorer

[MarcosNicolau]

Description

Adds periodic fetches for aggregation mode events and stores data structures in db.

How to run

1. Build db: make explorer_build_db
2. Run db: make explorer_run_db
3. Run migration: make explorer_ecto_setup_db
4. Run explorer: make run_explorer
5. Verify the data is added via psql:
   • docker exec -it explorer-postgres-container psql -U explorer_user -d explorer_db
   • SELECT * FROM aggregated_proofs;
   • SELECT * FROM proofs_agg_mode WHERE aggregated_proof_number = N

Note: to test this you'll need to setup two new ENV vars:

• ALIGNED_PROOF_AGG_CONFIG_FILE: the config file for the aggregation service contract deployment
• BEACON_CLIENT: a beacon client for the network (public ones would not respond blob requests to me, so you'll have to get one for yourself probably).

i think it is more a general problem in the explorer, but in some moment we should improve logs

[MarcosNicolau]

I agree, we should improve the logs + add a ci for formatting.
