Adding validations to reject repeated owner or staking address

[IPadawans]

Changes

• Added new storage to store all metagraphs and fee addresses in both layers: Global and Metagraph.
• Implemented validation in StateChannel validations to reject snapshots with existing addresses.
• Updated the validation function to accept not only staking balances but also addresses.
• Added new validation in StateChannel validation to reject duplicate entries.
• Updated the current tests to ensure compatibility with the updates.
• Added validation on the endpoint to reject existing wallets. This provides an additional layer of validation, rejecting messages of existing wallets directly at the endpoint, resulting in two layers of validation.
• Added code to populate existing metagraphs and addresses based on the lastGlobalSnapshot, and to fill values as snapshots are accepted.
• We decided to not change the schema to add the addresses OWNER and STAKING, so we are deserializing the binary to read those information

Tests

I've made tests in both scenarios, genesis and rollback in global layer
