fix: move hamburger menu after CV icon and change section icons to dark gray

**Position Fix:**
- Moved hamburger button to appear after the CV icon instead of before
- Order is now: CV icon → Hamburger → Title → Language selector
- Updated margin to 0 0.5rem for proper spacing between elements

**Icon Color Fix:**
- Changed section title icons from blue (--accent-blue) to dark gray (--text-gray)
- Maintains consistency with overall design
- Menu item icons still use gray by default, blue on hover
