Subject: [PATCH] fix: add missing version property to logs_build/host.json for
 Azure Functions v4

The logs_build/host.json was missing the required "version": "2.0" property
and used the deprecated v1 "eventHub" key instead of the v2+ "eventHubs" key.
This causes Azure Functions v4 runtime to fail with:
  "The host.json file is missing the required version property."

Changes:
- logs_build/host.json: Add "version": "2.0", extensionBundle, rename
  "eventHub" to "eventHubs" with v2+ config keys, add logging config
- metrics_build/host.json: Normalize indentation for consistency

The logs_build/host.json now matches the structure of metrics_build/host.json
(which was already correct).

Fixes #136
