cover the Phase 2 Claude surface to clear the 95% floor

The team cockpit / chat / config-tab work landed under-tested and pulled
total line coverage to 94.32%. Add tests for the team chat sidebar + pane
(@-completion, overlay, interrupt, message rows), the config loaders, the
stream-json MCP/streaming/rate-limit paths, and the conversation/prompt
card variants — restoring the total to 95.06%.
