See which Ramp bills need action first

**Objective:** Review the Ramp bills due in the next {days-ahead} days (default 14), optionally only for vendor `{vendor-name}`, and tell the user which need action first.

**Step 1: Pull the bills**

Call `ramp-get-bill` with `due-date.from` set to today and `due-date.to` set to today plus the window. If a vendor name was given, also pass it as `vendor-name.contains`. Set `max-records` to 200. If nothing is returned, say so and stop.

**Step 2: Flag the problems**

* Overdue or due within 3 days and payment status not paid: urgent.
* Approval status not approved: blocked, the bill cannot be paid until approved.
* Sync status showing the bill has not synced to accounting: note it.
* Several bills from one vendor in the window: group them and total them.

**Step 3: Report**

A table sorted by due date: vendor, invoice number, amount, currency, due date, approval status, payment status, sync status, and a one-line action. Finish with totals per currency and the three bills that need attention first.

**Rules & Guidelines:**

* Read only. Never call any `ramp-bill-*` write tool, `ramp-bill-archive` included.
* Never add amounts of different currencies together.

**Validation:**

* If the window is not a positive whole number, use 14 and say so.
* If more than 200 bills come back, say the list is truncated and ask for a narrower window.
