[remove endpoint] fix: remove cloudos job cost command; confirm archive teamId param (api-server#5665)

[Copilot]

Syncs cloudos-cli with two endpoint changes from api-server PR #5665 (54324c6f).

Overview

• GET /api/v1/jobs/{job_id}/costs/compute was removed from the API → drops cloudos job cost command and its implementation
• PUT /api/v1/jobs spec now formally requires teamId query param → existing code already sends it; no functional change needed

JIRA

• N/A (API contract sync)

Changes

• Removes @job.command('cost') from cloudos_cli/jobs/cli.py and its CostViewer import
• Removes get_job_costs and display_costs from cloudos_cli/cost/cost.py; retains standalone utility methods (_calculate_runtime, _format_storage, _format_price, _format_lifecycle_type)
• Updates tests/test_cost/test_job_cost.py: drops tests for deleted methods; adds test_get_job_costs_not_available and test_display_costs_not_available asserting the removed interface is gone
• Removes "Get Job Costs" README section and TOC entry
• Bumps version 2.91.0 → 2.91.1; adds CHANGELOG entry

Acceptance Criteria

Scenario 1 — `cloudos job cost` no longer listed

$ cloudos job --help
# 'cost' command absent from Commands list

Scenario 2 — archive/unarchive still sends teamId correctly

PUT /api/v1/jobs?teamId=<workspace_id> still issued by both cloudos job archive and cloudos job unarchive — no regression.
