Added a leadership section + cleaned up the awards

so i finally added a leadership section to my portfolio. new LeadershipSection.jsx component plus the data lives in portfolio-data.js like everything else. it covers my three 4-H roles: secretary & mentor, leading the curriculum redesign, and co-founding the summer learning program. i also redid the awards/recognitions section. it used to be a boring 2-column grid of cards, now its a vertical timeline with little icon dots running down a gradient line, and i threw in a few more awards while i was at it. hooked the new section into Portfolio.jsx (its between education and tech stack) and added an “Awards” link to the navbar with a smooth-scroll fix.

heads up: the diff looks huge (like 758 added / 537 removed) but honestly most of that is just prettier reformatting my navbar and recognitions files into double-quotes and multi-line jsx. the actual new stuff is way smaller than it looks.

the annoying part: somehow my package.json downgraded react-quill from ^2.0.0 all the way down to ^0.0.2 when the lockfile regenerated. definitely not on purpose, gotta revert that before it breaks something. also i split this into two commits and forgot the LICENSE file, so that got shoved into a random “pushing last few edited files” push lol.
