This change removes all code, configuration, and documentation related to
legacy networking (non-P2P) and mixed P2P/legacy modes. The following
updates were made:

- Dropped ENABLE_LEGACY and MIXED_P2P environment variables and logic
  from scripts and documentation.
- Removed legacy topology generation and handling in Python code.
- Updated template configs to always enable P2P and set related fields.
- Simplified cluster setup and node config editing scripts to only use
  P2P topology files.

This streamlines the codebase and ensures all clusters use P2P
networking exclusively.

## Description
<!--- Describe your changes -->
- Adds a new /pool_invalid_delegators RPC. This fetches any invalid
delegations for a given pool and epoch.
- /pool_delegators now returns valid delegations even if they have 0
balance
- /pool_delegators no longer returns invalid delegations
- /drep_info returns a new `drep_status` field instead of `registered`,
aligned with /pool_info
