refactor(deployment): collapse attestation evidence reports by default

[baktun14]

Why

The attestation evidence modal rendered every CPU/GPU report fully expanded, so a multi-GPU lease dumped several large base64 blobs at once and pushed the verdict badges and actions below the fold. Collapsing each report by default keeps the modal scannable while leaving the raw evidence one click away.

Replicates console-air #40. Part of CON-552.

What

• Each CPU/GPU report is now a collapsible row, collapsed by default. The verdict badge stays in the always-visible row header; the raw base64 report and verdict detail are revealed on expand.
• Removed the standalone "Platform" row and the "GPU reports (N)" heading.
• GPU rows are labelled 1-based ("GPU 1", "GPU 2") while still keyed on the 0-based device_index.
• Updated the modal spec to drive the new collapse/expand interaction; the validation flow stays on the generated Console API client.

Stacked on top of #3365.
