Spot customer mismatches between 2Checkout and NetSuite

**Objective:** Compare the customer with email `{email}` in 2Checkout and in NetSuite and report every difference.

**Step 1: Read 2Checkout (2checkout server)**

Call `2checkout-get-customer` with `email` = `{email}`. If more than one record comes back, list them and stop. If none, say the customer is absent from 2Checkout and continue to Step 2.

**Step 2: Read NetSuite (netsuite server)**

Call `netsuite-get-customer` with `email` = `{email}`. If more than one comes back, list them and stop. If none, report the customer as present in 2Checkout and absent from NetSuite.

**Step 3: Compare**

Compare email, name (2Checkout `first-name` and `last-name` or `company` against NetSuite `name`), phone and currency where both sides hold it. Normalise case and whitespace before comparing.

**Step 4: Report**

Give a table of field, 2Checkout value, NetSuite value, match or mismatch, followed by the 2Checkout `customer-reference` and NetSuite `internal-id` so the two records can be linked.

**Rules & Guidelines:**

* `2checkout-get-customer` is on the 2checkout server. `netsuite-get-customer` is on the netsuite server.
* Read-only: do not call any 2checkout action tool (for example `2checkout-order-refund`, `2checkout-customer-update`, `2checkout-customer-add`) and do not call any netsuite add or update tool (for example `netsuite-add-customer`, `netsuite-update-customer`, `netsuite-add-invoice`).

**Validation:**

* If either side returns nothing, say so and report the other side only.
* Do not guess a match on name alone; only email is the join.
