ci: enforce measured test coverage baselines

[KostasCherv]

What

• run the backend suite with pytest-cov and enforce the measured 73% floor
• run the complete UI source tree through Vitest V8 coverage with per-metric floors
• upload backend Cobertura XML and UI LCOV/JSON reports as CI artifacts
• document local coverage commands and the baseline policy

Why

Coverage was not measured in CI, so regressions could land silently. These thresholds are based on the current test suite rather than an arbitrary aspirational target and can be raised as coverage improves.

Impact

• backend CI fails below 73% statement/line coverage (current: 73.55%)
• UI CI fails below 19% statements, 19% branches, 12% functions, or 20% lines (current: 19.08%, 19.94%, 12.70%, 20.74%)
• coverage outputs are available for inspection on every workflow run

Checks

• 554 backend tests pass with coverage gate (73.55%)
• 8 UI tests pass with all four coverage gates
• Ruff passes
• UI ESLint and TypeScript checks pass
• graphify update . completed
