Add resources wiki UI, data, styles & search

Introduce a wiki-style Resources section: add includes for home, page, and sidebar layouts; expand _data/resources.json with many new resource entries (databases, hosting, SEO, security, etc.); add multiple category markdown pages under resources/; remove todo.txt. Refactor and extend SCSS (_sass/klise/_resources.scss) to implement responsive wiki layout, sidebar navigation, card/list styles, empty states and dark-mode overrides. Update site JS (assets/js/site-enhancements.js) to replace the old resources search with new global and section-specific wiki search/filtering logic and empty-state handling.
