v0.4.1: harden ISO uploads and beta UI polish

Add browser-safe chunked ISO uploads with progress, partial-file visibility, offset validation, and abort cleanup while keeping the legacy multipart endpoint for API clients.

Record host-log validation coverage, keep the queue/status UI copy clean, move release docs to 0.4.1, and tighten the dark theme to a near-black Netbox-style palette.
