fixes issues with data extraction

[tomjemmett]

• files were being created as inputs-data/inputs-data/dev, stopped the duplication of the container name
• we were not removing previous files, which could cause issues if the files were not overwritten

Pull request overview

Fixes issues in the data extraction upload process to prevent incorrect container path duplication and to ensure old extracted files are removed before uploading new ones.

Changes:

• Switch blob uploads to use a container URL directly (via ContainerClient.from_container_url) to avoid inputs-data/inputs-data/... style duplication.
• Add a pre-upload delete of the target extract_version directory using the ADLS Gen2 (Data Lake) API.
• Add azure-storage-file-datalake as a dependency (and lock it in uv.lock).
