Add L2 Specific data

### Implementation ideas

Atlas currently functions as a generic EVM block explorer. It lacks features specific to L2 rollups,
  such as:

  - Data Availability (DA) inclusion status
  - Sequencer details
  - Gas fee breakdowns (L1 vs L2 costs)

  Potential approach:
  Use https://github.com/evstack/ev-metrics as a data source for L2-specific metrics.
