tui.go (1032→164) and tab_sites.go (993→482) violated "small functions" and "testable in isolation" standards. Extracted 6 new files by concern: - format.go: pure formatting functions (fmtLatency, fmtUptime, etc.) - sparkline.go: sparkline rendering (latency, heartbeat, group) - update.go: Update method decomposed into 15 named handlers - view_dashboard.go: View, dashboard composition, tab bar, footer - view_detail.go: site detail panel - data.go: data refresh with extracted sortSitesForDisplay/filterSites Added 17 unit tests for the newly-testable pure functions covering format, sparkline, sort ordering, and filter logic. No behavioral changes — strict move-and-extract refactor.
