feat: adding Dark mode support

[ayushHardeniya]

The app only has a light theme right now.
for a mental health app, dark mode would be really helpful - easier on the eyes, especially at night.

we're using Tailwind, which has built-in dark mode support.
We'd need to:

1. Add a theme toggle button (sun/moon icon)
2. store the preference in localStorage
3. add dark: variants to all the components
4. Make sure it works with the existing color scheme

I'm willing to take this on but it's a decent amount of work since we'd need to update every component. Would appreciate help or at least confirmation this is wanted before I start.

also - should dark mode be the default?

a lot of mental health apps default to dark.
