[W9-3c] Enrich project table with task counts + CI-watch badge (#531)

Backend: ProjectSummaryResponse gains task_counts (done/active/blocked) + ci_watch_enabled. ProjectService.task_counts_for_projects does one GROUP BY project_id over TaskTable for every distinct project_id in the list (a project with no tasks is absent — route falls back to None). ci_watch_enabled is read straight off the Project row (already a column) — a 0-cost schema extension, honest signal that CI-watch is armed, no live-conclusion fan-out. project_to_summary takes an optional task_counts. No migration.

Frontend: ProjectTable gains a Tasks column (done/active/blocked + health dot, amber at-risk when blocked>0) and a CI-Watch badge under the project name when ci_watch_enabled. Both desktop Table and mobile ResponsiveTableCard variants. Mock projects carry the new shape (two sample repos).
