Feature request: expose billing and usage in the CLI

[dentiny]

Hi crusoe team, I found Crusoe v1 API exposes billing and usage endpoints, but CLI v1.0.4 (which is the latest release) does not provide billing, cost, or usage commands.

Existing API endpoints include:

• GET /v1/organizations/{organization_id}/billing/costs
• GET /v1/organizations/{organization_id}/billing/options
• GET /v1/organizations/{organization_id}/billing/export-productline
• GET /v1/organizations/{organization_id}/usage
• GET /v1/organizations/{organization_id}/usage/export

Suggested CLI interface:

crusoe billing costs \
  --start-date YYYY-MM-DD \
  --end-date YYYY-MM-DD \
  --project-id PROJECT_ID \
  --json

crusoe billing export \
  --start-date YYYY-MM-DD \
  --end-date YYYY-MM-DD \
  --output costs.csv

crusoe usage list \
  --start-date YYYY-MM-DD \
  --end-date YYYY-MM-DD \
  --project-id PROJECT_ID \
  --json

crusoe usage export \
  --start-date YYYY-MM-DD \
  --end-date YYYY-MM-DD \
  --output usage.csv

Expected dimensions:

• date
• project
• region
• resource/product type
• billable metric
• quantity
• unit price
• cost
• reservation ID

crusoe reservations list --json exposes point-in-time reservation utilization, but it does not expose historical billable usage or costs.

It would also be helpful if the CLI inferred the organization from the authenticated profile and supported table, JSON, and CSV output.
