fix(dashboard): replace emoji icons in tabs-context and tabs-other components

- tabs-context.js: package, clipboard-list, building-2, code-2, file-code, link, flask-conical, eye icons
- tabs-other.js: file-text, ruler, eye, blocks, package, git-branch, plug icons for exploration sections
- Update all empty state icons to use Lucide
- Update asset category icons (documentation, source code, tests)
- Update exploration titles with Lucide icons
