feat(kanban): convert inline-create title input to multiline textarea

- Changed Input component to native textarea for task creation
- Removed Enter-to-submit behavior (use Create button instead)
- Added proper styling: border, padding, rounded corners, focus ring
- 2-row default height with vertical resize and max-height cap
- Escape still cancels the form
