The checkmark in the Appearance theme menu was rendered server-side
(if user.Theme == opt.Name), so it never moved after switching themes
in the browser.
- Always render the check for every theme option, hidden by default,
using a new themeCheckClass(name, current) helper that returns the
hidden class unless the option is the active theme.
- Give each theme button a data-theme attribute and add
updateThemeIndicators() to web/src/theme.ts, which reads the applied
theme from the body class (theme-<name>) and toggles the hidden class
on each check accordingly.
- Call updateThemeIndicators() from changeTheme (before the async save
and on failure), initializeTheme, and loadUserTheme so the menu stays
in sync with the applied theme.
- Add unit test for themeCheckClass (templates/utils_test.go) and
regenerate templ output.
