Session 2026-05-29: tasks page redesign, projects sidebar, invoicing fix

- Tasks page: tabs (All/To Do/In Progress/In Review/Completed) in header, removed grid view, 70/30 split with projects card
- Projects card: sortable table, dynamic height fills viewport
- Removed Projects page and nav links; redirects → /tasks
- Invoice dedup: prevent double-charge when multiple submissions per revision version
- Dashboard table style applied to tasks table (10px headers, 5px cell padding, transparent cells)
- stat cards: removed "Tasks" header, moved Total Tasks to far right
