fix: better web controls

[dannyhw]

Issue: #280 #281 #283

What I did

• select now uses default select html when on the web platform
• date picker now uses local-datetime input on the web
• color picker now color input type on the web
• some ui improvements for the color picker on device

How to test

run the example app on web,android and web to check everything is still working

The color input seems nicer :)

For the datetime picker, it seems to work fine if I change the value by clicking the calendar icon, but not if I try to type in the values directly. For example, if I want to input 22/01/2022, I cannot input 22 in the day field. Should we also cater for the case of direct input?

@raychanks I agree its not ideal, though I had some issues making the typing version work. I'm thinking to merge this just to make something work and then add a task to improve it. Thats because currently it just doesn't work on web so something is better than nothing.
