Wallet top-up history

# Instructions — Wallet top-up history

## ⚠️ Date format: full ISO 8601 + timezone recommended

The MCP documentation states that YYYY-MM-DD alone is not accepted and that a full datetime is required.
In practice, `from="2026-06-01"` is accepted by the API (tested live — 16 results returned).

**Despite this tolerant behavior, always use full ISO 8601 with timezone:**
```
from: "2026-06-01T00:00:00.000Z"
to:   "2026-06-30T23:59:59.999Z"
```

Reason: coercion from YYYY-MM-DD to midnight can produce unexpected results depending on the server's timezone. Using `T00:00:00.000Z` (UTC) is unambiguous.

## ⚠️ Not for exact bank reconciliation

`get_wallet_loads` returns the **Spendesk record date**, not the **bank value date**.
→ Do not use it to align Spendesk balances with a bank statement.
→ For exact reconciliation, cross-check with your bank.

## ⚠️ 24h cache (86400 seconds)

The returned data may be up to 24h stale.
→ Do not use for a real-time balance — use `get_wallet_summary` for that.

## Step 1 — Call with period and recommended parameters

```json
{
  "companyId": "...",
  "from": "YYYY-MM-DDT00:00:00.000Z",
  "to": "YYYY-MM-DDT23:59:59.999Z",
  "pageSize": 100
}
```

## Step 2 — Interpreting the fields

For each load:
- `amount`: `{ amount, currency, precision }` → amount = `amount / 10^precision` EUR
- `type`: `"wireTransfer"` (only type observed on this account)
- `bankName`: `sfs` | `adyen` | `other`
  - `sfs` = Spendesk Financial Services (main account)
  - `adyen` = Adyen (accounts for certain subsidiaries)
  - `other` = external transfer
- `createdAt`: date recorded in Spendesk (≠ bank value date)

## Step 3 — Pagination

Check `meta.pagination.hasNextPage` — if `true`, paginate with `page=2, 3, ...` and the same filters.

## Live example (real data, June 2026)

16 loads in June 2026, including:
- 2026-06-23: EUR 500,000.00 (sfs transfer)
- 2026-06-10: EUR 600,000.00 (sfs transfer)
- Total for the month: ~EUR 1,105,721 (including two large test loads)

## Example prompt

- "Show wallet top-ups from last month" → from/to = last month + ISO 8601
- "How much did we load into the wallet in 2026?" → from=2026-01-01T00:00:00.000Z, to=today + pagination
- "What is the current wallet balance?" → use `get_wallet_summary`, not `get_wallet_loads`
