fix(desktop): align usage activity with model calls

[liuxiaocs7]

Summary

• source Usage Statistics from the selected Runtime Host's canonical Usage authority, matching Daily Review's model-call accounting
• label the combined model/tool table as an activity log and preserve aborted or unknown fields
• load every model and tool activity page and discard stale results when the selected Host or range changes
• seed canonical Usage records for the Desktop fixture and add regression coverage for the 151 model calls + 171 tool calls case

Fixes #3695
