feat: dark theme + toggle

LEstradioto commented 1 month ago

This PR is intended to start dark mode and toggle button (Nice addition with vanilla css!)

Changes

light and dark CSS variables and updated hard-coded to use variables (tough to apply dark theme at flatpickr + tom select, it required lots of lines !!!)
add toggle button on footer sidebar, toggle controller provides theme switching, system/theme persistence, smooth animate transition (is it too much?)
changed precedence at _javascript.html to override flatpickr and tomselect
changed margin and image size on nested fields
