feat: Enhance ERC registry update with efficient merge and deduplication

[quiet-node]

Description:
This PR introduces a mechanism to properly insert new, previously unrecognized ERC contract IDs into a sorted registry, ensuring that they are placed in the correct position based on their contract ID order. This change ensures that the registry remains correctly ordered, even when contracts missed by the tool are added manually.

Key Changes

1. Enhanced mergeAndSort Method

   • The mergeAndSort function ensures that new contract entries, including previously unrecognized contracts, are inserted into the appropriate position in the registry while maintaining the ascending order of contract IDs.
   • Contracts are merged and duplicates are removed automatically.

2. Improved updateRegistry Method

   • The method reads the existing sorted registry, merges it with newly identified contracts (including missed ERCs), and ensures the registry is correctly sorted by contract ID.
   • If new contracts are identified that should be inserted in a particular position, the method places them in the right place in the sequence, preserving the order.

3. Handling Missed Contracts

   • New contracts (previously unrecognized or missed by the tool) are now handled seamlessly, ensuring that contract IDs are inserted in their correct position without disrupting the existing sequence.

Fixes #1130
