Landing page UI bugs

[custosDiretriz]

• Align existing animations With figma design and implement new animations from the figma design
• fix lunch custos dapp button to display the lunch dapp modal instead of going to the services route
• fix button width and colours

[mercykolapo]

• [x] Give the header a heavier blur

• [ ] Fix the star on the launch Custos Dapp button

• [ ] On hover, button changes to blue

• [x] The launch dapp button under agreement is opening a modal instead of redirecting to the agreement page. I think the button text should be changed to lcreate agreement and record video respectively.
