🎨 style(ui): enhance dashboard statistics cards presentation

- Replace emoji icons with Semi Design Avatar components
- Standardize statistics cards layout across TokensTable and LogsTable
- Remove informational text banners for cleaner interface
- Implement consistent grid layout for metric cards
- Add elevated shadow effect to white Avatar for better contrast

Changes include:
- Convert emoji indicators to Semi Icons (MoneyExchangeStroked, Pulse, Typograph)
- Unify card styling with rounded corners and hover shadows
- Implement responsive grid layout (1 column on mobile, 3 columns on desktop)
- Standardize typography and spacing across all stat cards
- Apply Semi Design's elevated shadow to improve white Avatar visibility
