Done for schedule and typewriter. TBD: check other files

[rgbayrak]

Can you explain what has been done for this PR (during the cleanup) in details? @shansitads

We should probably do this for all issues. @dgzct11 @mashcodes10

[shansitads]

• removed duplicate components
• removed duplicate images and streamlined all into public/assets
• organized styling into page-wise css files for tabs with a lot of styling code
• combined index.css and style.css into index.css
• all common css styles remain in index.css
