style(tangle-dapp): Design changes in jam meeting

[yurixander]

Summary of changes

Provide a detailed description of proposed changes.

• ➕ The sidebar now automatically closes when a link is clicked.
• 🔧 Some wallets (such as MetaMask) allow for dApp usage on mobile via a built-in browser. However, our current Connect Wallet modal does not allow mobile users to connect their wallets. Fixed that.
• 🎨 Implemented and completed the design jam meeting changes across different components, improving design details, spacing, colors, and more.
• 🎨 Improved table consistency by explicitly defining 4 different table variants, so that they can be reused without custom class names.
• 🎨 Improved the loading spinner icon and animation to look more modern and fitting within the dapp.
• 🎨 Increased sizing of tooltips and made general legibility & readability improvements.
• 🎨 Applied container consistency across pages: Liquid staking cards, bridge, and restaking operations.
• 🎨 Other misc. small design bug fixes and improvements.

The page layout loading for bridge doesn't look like the bridge actually looks though ya?
