DIGIT-3155 Add cycle KPI page with burndown, label, and status charts

[gustoliveira]

Description ✍️

This PR adds a new KPI entry point for each cycle rows and introduces a dedicated cycle KPI page under the cycle detail route.

Main changes included:

• Added a new KPI action in the cycle list row, placed between the favorite star and quick actions menu.

• Added the new route:
  /${workspaceSlug}/projects/${projectId}/cycles/${cycleId}/kpi

• Created the cycle KPI page shell and initial KPI experience inside the existing cycle detail layout.

• Added an estimate-point burndown chart for cycles, explicitly using estimate points instead of issue count.

• Added client-side filtering for the KPI view by:

  • labels
  • assignees

• Added KPI summary cards for:

  • business days left / cycle ended
  • cycle dates
  • estimate scope
  • completed points
  • remaining points

• Added a points-by-label bar chart.

• Added a points-by-status bar chart.

• Added issue-level tooltip details for label and status charts.

• Extended the shared area chart types/component to support explicit x-axis ticks, interval, and tick-gap control needed by the KPI burndown chart.

Behavior details:

• Cancelled issues do not burn down the KPI burndown chart.
• Estimate-less issues do not affect point-based KPI calculations.
• Late completions are handled so KPI totals stay aligned with burndown semantics.
• The KPI chart highlights weekend x-axis labels and forces daily tick rendering for cycle dates.

Overview 👀

This PR introduces a new KPI screen for cycles with:

• direct navigation from the cycles list
• estimate-point burndown visualization
• filterable KPI analysis by assignee and label
• additional label/status point distribution charts with issue breakdown tooltips

How to Smoke? 👷‍♂️

1. Open the project cycles list on desktop.
2. Verify each cycle row shows a KPI button between the favorite star and the three-dot actions menu.
3. Click KPI and confirm navigation goes to:
   /${workspaceSlug}/projects/${projectId}/cycles/${cycleId}/kpi
4. Confirm clicking KPI does not trigger the parent row click behavior.
5. On the KPI page, verify the estimate-point burndown card renders inside the cycle detail shell.
6. Confirm the summary cards show cycle dates, business-days status, estimate scope, completed points, and remaining points.
7. Test label and assignee filters and confirm the burndown updates accordingly.
8. Confirm a filter combination with no matching issues shows the expected empty state.
9. Confirm a cycle with no estimate points shows the expected empty state.
10. Confirm the points-by-label chart updates with the active filters.
11. Confirm the points-by-status chart updates with the active filters.
12. Hover bars in both bar charts and verify the tooltip shows the related issues.
