BUG: CCIP router address assertion fails on local Hardhat network

### Is there an existing issue for this?

### Issue Description ✍️

## 📌 Describe the Bug
While running the test suite on a fresh local Hardhat setup, one of the ElectionFactory deployment tests fails due to a CCIP router address mismatch.

The failure seems to occur because the test expects a specific router address, which does not match the router deployed or mocked on a local Hardhat network.

## 🚨 Actual Behavior
Running `npx hardhat test` on a local Hardhat network causes the following test to fail:
ElectionFactory → Deployment → "Should set the ccip receiver router"
The assertion compares two different router addresses and fails, even though the contract deployment itself succeeds.

## 🎯 Expected Behavior
On a local Hardhat network, the test should either:
- use the locally deployed / mocked CCIP router address, or
- be skipped or handled differently if it is intended only for testnet or live environments.

## 💡 Suggestions
I’m not sure what the preferred approach is here, but possible options could be:
1. conditionally skipping CCIP-related tests on local Hardhat networks, or
2. adjusting the test setup to use the locally deployed / mocked router.
