Set Azure Functions authLevel to function

[v-sabiraj]

Changed HTTP trigger authLevel from "anonymous" to "function" across multiple Function App configs to enforce function-level access. Updated JSON configs in Zoom, Zscaler Remediation-URL, Fortinet FortiGate playbooks, Cofense Intelligence, IllumioSaaS, and Infoblox data connector function definitions; also updated associated Zoom and Cofense connector ZIP templates. This hardens access to HTTP-triggered functions by requiring a function key instead of allowing anonymous calls.
