fix: remove redundant pie chart and fix token allocation data discrepancy

🔧 Removed Redundant UI Elements:
- Removed token allocation overview pie chart from spend tokens page
- Chart was redundant since monthly token allocation card already shows composition chart
- Cleaned up unused TokenPieChart import

🔧 Fixed Token Allocation Data Discrepancy:
- Updated spend tokens page to use same API as header and composition bars (/api/tokens/balance)
- Previously used /api/tokens/allocations which had stale data
- Now ensures consistent token allocation display across all components:
  * Header token pie chart ✅
  * Recent edits composition bars ✅
  * Spend tokens page allocations ✅

🎯 Data Consistency Improvements:
- All token displays now use TokenBalanceContext data source
- Eliminates discrepancy between header/composition bars (A) and spend tokens page (B)
- Ensures most up-to-date token allocation data across entire app

All changes tested with successful build ✅
