Add dedicated Spouse section to individual person view

Enhanced the person detail page with a proper Spouse relationship section
to match the existing Parents, Siblings, and Children sections.

Features:
- Dedicated "Spouse" section between Parents and Siblings
- Clickable link to spouse's person page if in family tree
- Displays spouse metadata (generation, Kekulé number, lifespan)
- Shows "not in family tree data" note for spouses not in GEDCOM
- Consistent styling with other relationship sections

This makes spouse information more prominent and easier to find,
improving navigation between married couples in the family tree.

Previously spouse was only shown inline in the vitals section.
Now it has its own dedicated section for better visibility and
consistency with how other relationships are displayed.
