fix(research): Use cursor-based pagination for fetching ALL transfers

## Problem
- MCP tool has 50 transfer default limit (not 1000)
- `:limit` parameter wasn't being respected
- `:offset` pagination not supported by MCP endpoint
- Only fetching first 50 transfers regardless of pagination attempt

## Root Cause Analysis
MCP server uses **cursor-based pagination**, not offset-based:
- Response includes `nextPageSignature` field
- Next page requires `beforeSignature` parameter with cursor from previous response
- No support for numeric offsets

## Solution
Changed from offset-based to cursor-based pagination:

**Before (broken):**
```lisp
(get_account_transfers {:address addr :limit 1000 :offset 1000})
```

**After (working):**
```lisp
;; First page
(get_account_transfers {:address addr :limit 1000})
;; Get nextPageSignature from response

;; Next pages
(get_account_transfers {:address addr :limit 1000 :beforeSignature cursor})
;; Repeat until nextPageSignature is null
```

## Implementation
- Loop condition: `(while (or is_first_page next_cursor))`
- Dynamically build params based on page (with/without beforeSignature)
- Accumulate all pages: `(set! all_transfers (append all_transfers batch))`
- Continue until `nextPageSignature` is null

## Expected Impact
- Will now fetch ALL wallet transfers (not just first 50)
- Handles wallets with 1000s of transfers via proper pagination
- Aggregation will work on complete dataset
