Update Decap CMS to display individual tasks instead of BLOCKERS/BACKLOG files

- Changed TASKS collection from 'files' to 'folder' type
- Points at docs/tasks-active/ for individual task files
- Each task shows as separate entry in CMS
- Sortable by priority, status, task number
- Filterable: blockers, high priority, in progress
- Summary shows: Title (P# BLOCKER if applicable)

Fields Added:
- task_number (required, integer)
- title, priority, status, is_blocker
- tags, estimated_hours, completed_date, blocked_by
- body (markdown for task details)

UI Improvements:
- Blockers sort to top automatically
- Click task → edit just that task
- Mobile-friendly (individual entries vs giant files)
- Links to full specs in /docs/tasks/ preserved

Replaces:
- Old: Two files (BLOCKERS.md, BACKLOG.md)
- New: Individual task files in /docs/tasks-active/
