[Bug]: Empty NODE_BLS_KEY_PASSWORD error

[fdask]

What happened + What you expected to happen

Updated to the latest release on holesky, v0.8.5-rc.1 and encountered an issue starting the daemon. We keep getting the following error:
2024/12/17 14:48:26 application failed: BLS key file and password is required if BLS remote signer is disabled

We are using an empty password for our local BLS key. It appears this update checks that the key file name, and pass are NOT == "", which is leading to this.

Versions / Dependencies

v0.8.5-rc.1

How to reproduce

Use local bls key, with an empty password.

Issue Severity

High: It blocks me from completing my task.

@fdask we actually talked about this internally and want the testnet to be same as mainnet and enforce a password requirement. You can easily re-encrypt your keys using eigenlayer-cli with a password. Hope that helps
