Check a contact's Stripe billing before you call them

**Objective:** For the email `{contact-email}`, show who the person is in Salesforce and how they are billed in Stripe, looking back `{lookback-days}` days for charges (default 90).

**Step 1: Find the contact in Salesforce**

Call `salesforce-get-contact` with `email` set to `{contact-email}`. If nothing comes back, also call `salesforce-get-lead` with `email` set to `{contact-email}` and report the lead instead. If more than one contact matches, list them all.

**Step 2: Read the account and its open deals**

If the contact has an account-id, call `salesforce-get-account` with `account-id` set to it, and `salesforce-get-opportunity` with `account-id` set to it and `closed` set to false.

**Step 3: Find the Stripe customer**

Call `stripe-get-customer` with `email` set to `{contact-email}`. If nothing comes back, report the person as present in Salesforce and absent from Stripe and go straight to the report.

**Step 4: Read billing**

With the Stripe customer-id, call `stripe-get-subscription` (customer-id), `stripe-get-invoice` (customer-id, status open) and `stripe-get-charge` (customer-id, created.from set to today minus the lookback). Count failed charges, refunded charges and disputed charges.

**Step 5: Report**

Two short sections side by side in a table or two lists: Salesforce (contact name, title, account, account owner, open opportunities with stage, amount and close-date) and Stripe (customer-id, delinquent, balance, each subscription with status and current-period-end, open invoices with amount-remaining and due-date, charges summary). End with one line of what a rep should know before contacting this person.

**Rules & Guidelines:**

* `salesforce-get-contact`, `salesforce-get-lead`, `salesforce-get-account` and `salesforce-get-opportunity` are on the salesforce server. `stripe-get-customer`, `stripe-get-subscription`, `stripe-get-invoice` and `stripe-get-charge` are on the stripe server.
* Match emails case-insensitively and trimmed.
* This is read-only. Do not call `salesforce-update-contact`, `salesforce-update-account`, `salesforce-update-opportunity`, `salesforce-add-task`, `salesforce-add-case` or any other salesforce add or update tool.

**Validation:**

* If neither system knows the email, say so and stop.
* If the Stripe customer name and the Salesforce contact or account name clearly disagree, show both and flag it; do not decide which is right.
