UI: section-header / Edit Profile improvements

[rorar]

Hi! I would love to expand the Edit Profile modal a bit further with a few quality-of-life improvements:

• a link repeater field for social profiles and websites like website, XING, GitHub, Pinterest, and custom entries, with custom icon selection
• User option: replacing the current section-header color styling with a hero image for a more polished profile look (like LinkedIn)
• making the Edit About button jump directly to the Bio field anchor, so editing starts at the most relevant place right away

I think these additions would make the profile editor feel much more flexible and user-friendly. Happy to help shape the UX/details if needed!
