feat(chains): add Ethereum Hoodi network support

## Problem

KeeperHub does not currently register Ethereum Hoodi (chain ID `560048`), so workflows targeting the active Lido testnet are rejected before simulation or execution.

## Proposed change

Add Hoodi as an EVM chain with its aliases, public RPC default, explorer metadata, chain seed data, and Lido Hoodi stETH/wstETH recognition.

## Why it matters

Hoodi is Lido’s maintained testnet. First-class KeeperHub support enables deterministic workflow integrations to be safely dry-run and executed there.

## Implementation

A focused PR is ready and will be linked after this issue is accepted.

No files or tests are named in the issue. Start by locating the EVM chain registration and chain seed data, then trace how aliases, RPC defaults, explorer metadata, and Lido Hoodi stETH/wstETH recognition are represented. Done means chain ID 560048 is accepted with all requested metadata and token recognition, with the relevant tests passing.
