Match Ramp vendor credits to Business Central credit memos

**Objective:** For the vendor matching `{vendor-name}`, compare vendor credits in Ramp with posted purchase credit memos in Business Central, looking back from `{created-from}` (default: the last 365 days). Read-only.

**Step 1: Find the Ramp vendor**

Call `ramp-get-vendor` (Ramp server) with `name.contains` set to `{vendor-name}`. If more than one vendor matches, list them and stop for the user to choose.

**Step 2: Read the Ramp credits**

Call `ramp-get-vendor-credit` (Ramp server) with `vendor-id` set to the vendor's `id` and `created-at.from` set to `{created-from}`. Keep `reference-number`, `total-amount`, `total-applied-amount`, `remaining-amount`, `accounting-date`, `archived-at`. For credits with a non-zero applied amount, call `ramp-get-vendor-credit-applied-bill` (Ramp server) to see which bills they were applied to.

**Step 3: Read the Business Central credit memos**

Call `business-central-get-posted-purchase-credit-memo` (Business Central server) with `buy-from-vendor-name.contains` set to `{vendor-name}` and `posting-date.from` set to the same start date. Keep `credit-memo-number`, `vendor-credit-memo-number`, `amount-including-tax`, `posting-date`, `remaining-amount`, `applies-to-document-number`.

**Step 4: Match and report**

Match the Ramp `reference-number` to the Business Central `vendor-credit-memo-number`. Report: matched with equal amounts; matched with different amounts; Ramp credits with no Business Central memo; Business Central memos with no Ramp credit. For matched pairs, say whether the applied amount in Ramp agrees with the Business Central `remaining-amount`.

**Rules & Guidelines:**

* `ramp-get-vendor`, `ramp-get-vendor-credit` and `ramp-get-vendor-credit-applied-bill` are on the Ramp server; `business-central-get-posted-purchase-credit-memo` is on the Business Central server.
* Read-only. Do not call `business-central-create-purchase-credit-memo`, `business-central-update-purchase-credit-memo` or any Ramp write tool.

**Validation:**

* If the vendor has no credits in Ramp, still read Business Central and report its memos as unmatched.
* Skip archived Ramp credits from the unmatched list but mention how many there were.
* Compare amounts in the document currency; if currencies differ, say so instead of comparing.
