refactor: consolidate warp addresses (#513)

### Description

Remove `-addresses.yaml` files for warp deployments since addresses are
now maintained in config files. This change:
1. Removes warp-specific address YAML files
2. Removes warp address file generation functionality from registry
3. Updates registry tests to remove warp address file validation checks

This cleanup consolidates warp deployment addresses to a single location
in the config files.

### Related issues

### Backward compatibility

Yes - This is a cleanup of redundant warp address files. All warp
deployment addresses remain available in the config files.

### Testing

- Verified that all warp addresses previously in YAML files exist in
corresponding config files
- Updated and ran registry tests to confirm functionality without warp
address files
- Validated that CLI and other tooling continue to work with warp
addresses from config files
