[Feat] Trading History section on reader dashboard with pagination

[realproject7]

Feature: Add Trading History section to reader dashboard

Problem

We now index all MCV2_Bond mint/burn trades in the trade_history table, but the reader dashboard only shows a portfolio summary and donation history. There's no way for readers to see their trading activity.

Scope

Add a "Trading History" section to the reader dashboard, positioned above the Donation History section.

Data source

Query trade_history table filtered by the connected wallet address (need to match against the tx_hash → on-chain user field, or add a user_address column to trade_history if not already present).

Check first: Does trade_history currently store the trader's wallet address? If not, this ticket includes adding a user_address column and updating the trade indexer routes to populate it.

Display

Each record should show:

• Event type: "Buy" (mint) or "Sell" (burn)
• Token name/storyline link
• Amount of tokens traded
• Reserve amount (PL_TEST) paid/received
• Timestamp
• Clickable Basescan tx link (${EXPLORER_URL}/tx/${tx_hash})

Pagination

• Default: show 10 most recent trades
• "Load more" button to load 10 more
• Same pagination pattern as Donation History ([Feat] Clickable Basescan tx links on donation history + pagination #351)

Files to Investigate

• Reader dashboard page/component
• trade_history table schema (check for user_address column)
• src/app/api/index/trade/route.ts and src/app/api/cron/trade-history/route.ts — may need to add user_address

Branch

task/352-trading-history

Dependencies

• Should be implemented after or alongside [Feat] Clickable Basescan tx links on donation history + pagination #351 (donation pagination) to share the pagination pattern
