♻️ Refactor: Move token unit toggle from table header to filter settings

- Remove K/M switch from model price column header in pricing table
- Add "Display in K units" option to pricing display settings panel
- Update parameter passing for tokenUnit and setTokenUnit across components:
  - PricingDisplaySettings: Add tokenUnit toggle functionality
  - PricingSidebar: Pass tokenUnit props to display settings
  - PricingFilterModal: Include tokenUnit in mobile filter modal
- Enhance resetPricingFilters utility to reset token unit to default 'M'
- Clean up PricingTableColumns by removing unused setTokenUnit parameter
- Add English translation for "按K显示单位" as "Display in K units"

This change improves UX by consolidating all display-related controls
in the filter settings panel, making the interface more organized and
the token unit setting more discoverable alongside other display options.

Affected components:
- PricingTableColumns.js
- PricingDisplaySettings.jsx
- PricingSidebar.jsx
- PricingFilterModal.jsx
- PricingTable.jsx
- utils.js (resetPricingFilters)
- en.json (translations)
