Consolidate project notification jobs into unified daily digest

[redreceipt]

Summary

Consolidates three separate project notification functions (post_overdue_projects, post_upcoming_projects, and post_friday_deadlines) into a single unified post_project_updates function that runs daily and groups projects by status (overdue, ending soon, starting soon).

Key Changes

• Merged three jobs into one: Replaced three separate scheduled jobs with a single daily digest that covers all project statuses
• Unified filtering logic: Consolidated engineering lead validation and project status filtering into a single pass through projects
• Improved time windows: Changed from day-of-week specific scheduling (Monday/Friday) to a consistent 3-day window for both ending-soon and starting-soon projects
• Better organization: Projects are now grouped into three sections (Overdue, Ending Soon, Starting Soon) within a single Slack message, ordered by date within each section
• Simplified scheduling: Reduced from 3 scheduled jobs to 1 daily job at 14:00 ET
• Updated tests: Refactored test suite to reflect the new consolidated function with comprehensive test cases for filtering, grouping, and ordering logic

Implementation Details

• The new function processes all projects in a single loop, categorizing them into three lists based on their target/start dates and status
• Projects are filtered to only include those with engineering leads and active/planned statuses
• Overdue projects are identified using existing format_project_target_status helper
• Ending-soon and starting-soon projects use a consistent 3-day window (0-3 days from today)
• Only posts to Slack if at least one project matches the criteria
• Maintains backward compatibility with existing project data structure and Slack markdown formatting

Filter inactive projects from starting-soon section

post_project_updates only filters starting_soon by canceled status, so projects marked Completed, Incomplete, or Released (or with completedAt set under a non-canceled status) can still be announced as "Projects Starting Soon" when their startDate is within 0–3 days. This produces false Slack alerts for already closed work; the overdue/ending paths already use _is_inactive_project, so the starting-soon branch should apply the same guard.
