Add overdue tasks (Просрочена) to task dashboard

[konard]

Summary

• Adds Просрочена (overdue) KPI card between В работе and Отложена
• Shows overdue tasks in the monthly bar chart and legend
• Includes overdue count in summary totals and completion rate calculation
• Adds Просрочена column (id 155680) to fallback column definitions
• Reassigns Отложена to amber color; red is now used exclusively for overdue tasks

How to reproduce the issue

Open the task dashboard (templates/sportzania/taskdash.html). The report data (Дэшборд - Задачи.json) contains a Просрочена column, but the dashboard did not display it anywhere — not in KPIs, chart, or legend.

What was changed

Area	Change
KPI cards	Added "Просрочена" card (6th card, red icon)
Chart legend	Added "Просрочена" dot in red
Chart bars	Added overdue segment (red) per month
Summary calculation	overdue added to total
Fallback columns	Added id 155680 / name Просрочена
Color semantics	Overdue = red; Отложена = amber

Test plan

• Open the dashboard and verify the "Просрочена" KPI card appears
• Verify overdue tasks appear in chart bars (red segment)
• Verify the legend shows the red "Просрочена" dot
• Verify the "Всего задач" total includes overdue tasks

Fixes #2191
