Add 'In Progress' tab to history sidebar

Features:
- New "In Progress" tab shows running/pending jobs
- Displays active jobs without opening full queue
- Tab positioned first for quick visibility
- Shows "Running..." or "Pending" status
- No delete button on active jobs (only completed/failed)

Implementation:
- Updated BuildHistorySidebar to accept activeJobs parameter
- Converts queue.Job to ui.HistoryEntry for display
- Filters running/pending jobs from queue
- Conditional delete button (nil check)
- Dynamic status text based on job state

UX Improvements:
- Quick glance at current activity without queue view
- Three-tab layout: In Progress → Completed → Failed
- Consistent styling with existing history entries
- Tappable entries to view full job details

This allows users to monitor active conversions directly
from the history sidebar, reducing the need to constantly
check the full job queue view.
