Changed Cider and Clojure setup to Emacs Lips Idioms

[jobsam]

This merge request updates the Emacs Lisp configuration (init.el) to enhance the setup for Clojure development using CIDER and related tools. The changes ensure better package management, standard Emacs Lisp syntax, and improved integration with development workflows.

Changes:

Refactored package installation and initialization using package.el. Integrated lsp-mode, cider, company, and related tools for Clojure development. Configured key bindings, hooks, and mode settings for improved usability. Updated custom functions (cider-start-http-server, cider-refresh, cider-user-ns) for managing Clojure projects.
