chore(telemetry): provision real 1DS iKey + INT collector URL

Replace the PLACEHOLDER_REPLACE_BEFORE_SHIPPING value with the
provisioned iKey for tenant ffdb4c99... and point the dispatcher at
the Aria INT OneCollector endpoint. With this in place the dispatcher
takes the HTTPS POST path instead of writing to the local JSONL fallback.

The iKey is a write-only identifier, safe to commit in plaintext per
the design spec (Microsoft OSS precedent: VS Code, dotnet SDK, Azure
CLI). Both shared/telemetry/ikey.json and the synced plugin copy are
updated together.
