Introduces a dark-mode theme and toggle

[Copilot]

Pull request overview

Adds a DaisyUI-backed dark theme to the site and introduces UI controls to toggle between light/dark modes, persisting the choice in the browser.

Changes:

• Initialize the active theme via data-theme using localStorage and prefers-color-scheme.
• Add desktop + mobile theme toggle controls in the navbar.
• Register a new cakephp-dark DaisyUI theme and add dark-mode-specific CSS overrides (SlimSelect, navbar, placeholders).

Unfortunately we don't have a dark variant colorset on https://cakephp.org/logos but this feels pretty good to be honest.

Does this automatically use the dark theme if the browser has dark theme preferences set?

I could clean this up by targetting the "pie" path with the typical cake red color :)

Yes using prefers-color-scheme => https://github.com/cakephp/plugins.cakephp.org/pull/157/changes#diff-19efa77022d02e72d1c598ef2f2687da466c7459920c6a9460bfe4cc6c03ee6fR40
