Rahul Barman d814c029bb Fix checkpoint sync 401 with trailing-slash path-embedded API keys (#9548 )

Closes #9545


  `BeaconNodeHttpClient::eth_path` clones the configured server URL and pushes path segments onto it. When the base URL ends with a slash (such as a QuickNode-style endpoint that embeds the API key in the path, `https://<host>/<api-key>/`), the URL already carries an empty trailing segment, so pushing `eth` yields a double slash:

```
https://<host>/<api-key>//eth/v2/debug/beacon/states/finalized
```

The provider responds to the `//` form with a `307` redirect to a normalized path that drops the key segment, so the redirected request arrives unauthenticated and checkpoint sync fails with `Error loading checkpoint state from remote: StatusCode(401)`.

This PR calls `pop_if_empty()` before pushing segments, the standard `url`-crate idiom for trailing-slash-tolerant joining, so a trailing slash no longer changes the resulting path. The fix is applied in `eth_path` (the shared prefix builder that every `/eth/vX` endpoint derives from) and in `post_lighthouse_liveness`, the only other builder that extends the base URL directly.
