Fix bugs in aggregation workflow

[amrit110]

This pull request adds new per-team metrics to template analytics, specifically tracking the number of unique active users and the number of active days for each team using a template. These metrics are computed in the backend, included in the API, and displayed in the frontend. Additionally, the logic for aggregating these metrics at the company level has been updated for greater accuracy.

Backend: Per-Team Metrics Calculation

• The compute_template_metrics function now calculates team_unique_active_users and team_active_days for each template, based on daily engagement data and recent activity. [1] [2]
• The function signature and call site in main() are updated to pass the necessary engagement data. [1] [2]

API and Types Update

• The TemplateMetrics interface is extended to include team_unique_active_users and team_active_days.

Frontend: Display and Aggregation

• The new metrics are displayed per team in the template teams content component. (services/analytics/app/template/[templateName]/template-teams-content.tsxR74-R75)
• Company-level aggregation now sums unique_active_users across teams and takes the maximum of active_days across teams, instead of previous less-accurate methods. [1] [2] [3]
