Implement Unified Quick Add for Tasks tab (Phase 3 Step 8)

Add Quick Add form to create Todoist tasks or Trello cards directly
from the Tasks tab with optional due date support.

Features:
- HandleUnifiedAdd handler with due date parsing
- HandleGetListsOptions for dynamic Trello list loading
- Quick Add form with source toggle (Todoist/Trello)
- Date picker for due dates
- HX-Trigger refresh after successful creation
- Pass boards to tasks-tab template for board selector

Cleanup:
- Remove resolved issue tracking files
