theme: add nvtop, htop, and cava support (#45)

* templates: add nvtop, htop, and cava support

* Triggers htop and cava theme reloads

Sends a USR2 signal to htop and cava after their themes are applied. This prompts the applications to reload their configuration files, ensuring new themes are visible instantly without requiring a manual restart.
