Update the staking pool info page colours and skin tones.

[brunomenezes]

📄 Context

Here are the staking pool page checkboxes for changes in colour, skin tones and fonts in Dark mode to comply with the new Cartesi brand. The application's structure did not change, only the look and feel.

PS: Refer to the parent of this issue for references.
PS²: Don't worry about the header and footer, because that is addressed in a separate issue #62

📈 Subtasks

Overall

• Make sure the fonts are applied correctly based on the Figma description. i.e. Where to use each font and what size and weight to be applied.
• Make sure the components are round, like the design. We're transitioning from a squared-based design to a round one.

Page sessions

• Check if the new colour for the page name is correct. Apply changes if needed.
• Apply colour changes to the Summary space. i.e. Staking pool cards e.g. Users / Commissions./ Staked balance
• Apply colour changes to the Pool Activity space.
  • Update the look and feel of the search input
  • Update the colours for the filter and tag. That included the menu, checkbox and radio button.
