fix: Center adaptive icon logo horizontally

Fix horizontal alignment issue where the logo appeared slightly
left-aligned in the adaptive icon.

Root cause analysis:
- Original logo SVG has viewport 1024x1024
- Logo path content spans ~285-720px (center at ~502px)
- Logo is inherently off-center by ~10px in original viewport
- Previous centering calculation assumed logo was centered in viewport

Changes:
- Adjust scale from 0.061 to 0.0645 for better fit
- Increase translateX from 21.06 to 21.65 to compensate for logo offset
- Keep translateY at 21 (vertical centering is correct)
- Add detailed comments explaining the offset calculation

Result: Logo now appears properly centered in adaptive icon canvas
