Show task complexity on /tasks/<id> page

Perfect! The implementation is complete. Let me create a summary
of what

I have successfully implemented the task complexity indicator on the
`/t

1. **Added `complexityBadge` function** in `Omni/Jr/Web.hs`
(lines 685-6
   - Creates a badge displaying the complexity with the ℂ symbol
   (comple - Format: "ℂ {1-5}" - Includes a tooltip "Task Complexity
   (1-5)" - Uses CSS classes for styling with different colors for
   each complex

2. **Integrated complexity badge into task detail page** in
`Omni/Jr/Web
   - Added conditional rendering that only shows the badge if
   `taskCompl - Positioned after the priority badge with a separator
   (·) - Follows the same pattern as other metadata badges

3. **Added CSS styles** in `Omni/Jr/Web/Style.hs` (lines 696-713):
   - Base `.badge-complexity` style - Individual styles for each
   complexity level (1-5) with appropriate
     - Complexity 1: Green (easy task) - Complexity 2: Blue (moderate)
     - Complexity 3: Amber (medium complexity) - Complexity 4: Darker
     amber (high complexity) - Complexity 5: Red (very complex)

- Used the ℂ (complex numbers) symbol as suggested in the task
descripti - Made it non-editable (read-only badge) since complexity is
set during - Only displays when complexity is set (handles `Maybe Int`
gracefully) - Color scheme follows a gradient from green (easy) to red
(complex) - Consistent with existing badge styling patterns in the UI

✅ All tests pass successfully with `bild --test Omni/Jr.hs`

The feature is now complete and ready for use. Tasks with a
complexity r

Task-Id: t-207
