Design system updates

[smolenski-mikolaj]

• improve the up-down padding in the secondary button on the home page
• correct the primary buttons and gray buttons in the ripple documentation (currently there are older versions incompatible with those in the button documentation with my latest design)
• in charts in a dark theme, lighten the axes, labels and legend accordingly
• fix the primary button in the timepicker (there is an older version of the button): https://tst.tailwind-elements.com/docs/standard/forms/timepicker/#section-without-icon
• make a lighter background for the switch for the static fragment in the dark theme
• correct color active for caret (arrows) in select, because instead of new primary there is old blue: https://tst.tailwind-elements.com/docs/standard/forms/select/
• correct the primary button that launches the modal (there is an older version of the button) in the select documentation and in general correct both buttons in this modal: https://tst.tailwind-elements.com/docs/standard/forms/select/#select-inside -modal
• another improvement of the primary button in the select documentation: https://tst.tailwind-elements.com/docs/standard/forms/select/#select-with-toggle-element
• add corrected checkboxes in select: https://tst.tailwind-elements.com/docs/standard/forms/select/#multiselect, https://tst.tailwind-elements.com/docs/standard/forms/select/# select-with-placeholder, https://tst.tailwind-elements.com/docs/standard/forms/select/#set-value, https://tst.tailwind-elements.com/docs/standard/forms/select /#select-with-toggle-element
• fix "save" button in select: https://tst.tailwind-elements.com/docs/standard/forms/select/#custom-content
• correct border color and thickness in search in select: https://tst.tailwind-elements.com/docs/standard/forms/select/#search
• convert the range input to be closer to that in mdb
• reduce the contrast of the background and border in the radio button
• inputs with a floating label adjust the border to the dark theme, as in the basic inputs: https://tst.tailwind-elements.com/docs/standard/forms/inputs/#floating
• improve the inputs, especially in different input groups with buttons, the shadow of the border on the inner (inset) and the color of the border in the focus state, because currently it does not color on primary when in focus in a dark theme
• inputs in the dark theme version
• softer shadows for buttons in dark theme
• improved base shadows in dark theme version
