Add holders for TLOS itself - Create /accounts endpoint

Top Accounts by TLOS Balance Implementation

Problem

We need to display ERC20 holder data that exists in our database but lacks UI representation.

Proposed Solution

Create an /accounts page accessible from the Blockchain header navigation tab (last position).

UI Components

• Header: "Top Accounts by TLOS Balance"
• Stats Display: Total accounts with TLOS balance and total TLOS balance
• Data Table:

# | Address | Name Tag | Balance | Percentage | Txn Count

Table Requirements

• Sort: Descending by TLOS balance (fixed)
• Pagination: 25 items per page
• Address: Links to address page
• Name Tag: Shows Contract Name or empty string, non-clickable
• Balance: 2 decimal points
• Percentage: 2 decimal points
• Zero balance accounts excluded

Performance Requirements

• Load time: <1 second
• Scale: Handle 10k new accounts/day
• Caching: Implement as needed for performance
• Refresh: Maximum frequency without performance impact

Technical Requirements

• Responsive design matching existing tables
• Error states matching existing tables
• Standard pagination controls

Questions for Dev Team

• Do we have all required endpoints?
• Performance impact assessment needed for:
• Server
• Indexer
• Database
• Caching strategy requirements?
• Index creation needed?
• Do we want export functionality? @poplexity @jbuice
