fix: add type="button" to modal close buttons to fix Enter key form submission

Previously, pressing Enter in modal form inputs would dismiss the modal instead
of submitting the form because close buttons defaulted to type="submit". This
adds explicit type="button" to all modal close buttons to ensure Enter key
properly submits forms.

Fixes:
- New board creation via Enter key
- New workspace creation via Enter key
- New card creation via Enter key
- New list creation via Enter key
- Member invitation via Enter key
- Label creation/editing via Enter key
- Board URL updates via Enter key
- Import boards forms via Enter key
