chore(deps): bump @grafana/data and pin transitive deps to patched versions

- @grafana/data ^11.6.14 -> ^11.6.15 - http-proxy-middleware 4.0.0 -> 4.1.1 (dep + resolution) - form-data 4.0.4 -> 4.0.6 - tmp 0.2.4 -> 0.2.7 - add js-cookie ^3.0.7 resolution pin (forces react-use's transitive copy to a patched range)
