fix(todo): simplify section headers - remove chevron, count, and collapse

Sections are now always open with clean minimal headers:
- Remove chevron toggle icon
- Remove task count from section headers
- Remove collapsible behavior (sections always visible)
- Reduce icon size from 20 to 18
- Remove count from upcoming day subheaders
