refactor(web): receipt-style config panel and deployment status bars

[arjunkomath]

Summary

• Reworks the service details config panel (next to the charts) from a chip-heavy 2×2 card grid into a flat, receipt-style spec sheet: mono font, hairline dividers, key–value rows with muted labels for unset values, per-server instance rows.
• Restyles the pending changes banner and deployment/build progress bars in the same language: status dot + label header, mono field: old → new change table, amber/blue/red accent tint, and a thin stage-progress line on active rollouts and builds.
• Moves both bars below the service overview card, rendered as a sheet sliding out from under it (square top edge, no top border, no shadows), width-matched to the rollout history container.
• Abort button is now destructive red; redundant stage text ("Starting container", "Routing traffic") removed since the rollout row below shows it — migration and build stage labels kept, as they have no row below.

Testing

• tsc --noEmit and Biome clean.
• Visually verified in dev across pending changes, deploying, and live states (screenshots iterated in-session).
