v0.2.4 - Hotfix: Unknown status + copy UX + update banner context

Bug fix:
- config.py: empty PARAKEET_CONTAINER / MAGPIE_CONTAINER env vars (from migrating to v0.2.0+ where the field is optional and saved as '') now fall back to 'parakeet-asr' / 'magpie-tts' via the 'or' idiom. Confirmed live: services classify as 'running' instead of 'unknown'.

UX:
- Replaced text 'Copy' buttons with compact icon buttons (clipboard SVG)
- Endpoint Base URL + Model ID + curl snippet are now click-to-copy themselves (the value AND a separate icon button)
- Service cards: host, base URL, and model are now three separate copyable rows
- Update banner: leading explanatory line — 'Updates to eugr/spark-vllm-docker — the upstream project that orchestrates vLLM on your Sparks. These are not firmware, OS, or model updates.' with a link to the repo.
