feat(v1.8.0): IMPL_08 Widget - Fix Text Note Display Bug

- Change TextNoteFullView() to render individual lines instead of paragraphs
- Preserve empty lines as 8dp spacers for paragraph separation
- Add maxLines=5 per line item to prevent single-item overflow
- Increase preview limits: compact 100→120, full 200→300 chars
- Increase preview maxLines: compact 2→3, full 3→5 lines

Fixes widget text truncation bug where long text notes only showed
3 lines regardless of widget size. By splitting into individual line
items, LazyColumn can properly scroll through all content. Each line
is rendered as a separate item that fits within the visible area.
