Turn DonorPerfect gifts into a review-ready Business Central journal

**Objective:** Create one Business Central general journal line for each DonorPerfect cash gift dated `{from-date}` to `{to-date}` that is not already in Business Central, balanced against account `{balancing-account-number}`. Lines are staged in a journal for an accountant to review and post; this prompt never posts them.

**Step 1: Read the gifts in DonorPerfect**

Call `donorperfect-get-gift` with `gift-date.from` = `{from-date}` and `gift-date.to` = `{to-date}`. Raise `max-records` until the result stops growing. Keep record type G (gifts, including pledge payments) only. Drop pledge headers (P) and soft credits (S), and list any gift with a blank `gl-code` as "cannot stage: no GL code".

**Step 2: Check each gift is not already in Business Central**

Each gift is identified in Business Central by the document number DP-<gift-id>. For each gift:

* call `business-central-get-general-journal-line` with `document-number` = DP-<gift-id>, and
* call `business-central-get-general-ledger-entry` with `document-number` = DP-<gift-id>.

If either returns a row, the gift is already staged or posted. Mark it "skipped: already in Business Central" and do not create a line for it.

**Step 3: Check each GL code is a usable account**

For each distinct `gl-code` left, call `business-central-get-account` with `account-number` = that code. If the account is missing, blocked, not of type Posting, or has `direct-posting` false, mark its gifts "cannot stage: account <code> not usable" and leave them out.

**Step 4: Confirm with the user**

Show the plan before writing anything: the number of gifts to stage, their total, a summary by GL code, and every skipped or unstageable gift with its reason.

If `{journal-id}` is given, the lines go into that journal. If it is blank, propose creating a new journal with `business-central-create-journal` using code DP followed by `{to-date}` as YYMMDD, `display-name` "DonorPerfect gifts `{from-date}` to `{to-date}`", `template-display-name` GENERAL unless the user names another template, and `balancing-account-number` = `{balancing-account-number}`.

Ask the user to confirm. Do not continue without an explicit yes.

**Step 5: Create the lines**

If a new journal was agreed, call `business-central-create-journal` once and take `id` from the result as the journal id.

Then for each gift in the plan, call `business-central-create-journal-line` with:

* `journal-id` = the journal id
* `posting-date` = the gift's `gift-date`
* `document-number` = DP-<gift-id>
* `external-document-number` = the gift's `reference` when it has one
* `account-type` = G/L Account, `account-number` = the gift's `gl-code`
* `amount` = the gift's `amount` as a negative number (a credit to revenue)
* `balance-account-type` = G/L Account, or Bank Account if the user says `{balancing-account-number}` is a bank account; `balancing-account-number` = `{balancing-account-number}`
* `description` = "DonorPerfect gift <gift-id> donor <donor-id>", cut to 100 characters

Create lines one at a time. If a call fails, record the error against that gift and carry on with the next one.

**Step 6: Report**

A table of every gift: `gift-id`, `gift-date`, `donor-id`, `gl-code`, amount, outcome (staged with the new line `id`, skipped, cannot stage, or failed with the error). Then the journal id, the number of lines staged and their total. Remind the user that the journal still has to be reviewed and posted in Business Central.

**Rules & Guidelines:**

* `donorperfect-get-gift` is on the donorperfect server. `business-central-get-general-journal-line`, `business-central-get-general-ledger-entry`, `business-central-get-account`, `business-central-create-journal` and `business-central-create-journal-line` are on the business-central server.
* The only tools that may write are `business-central-create-journal` (at most once) and `business-central-create-journal-line`, and only after the user confirms in Step 4.
* Never change DonorPerfect. Do not call `donorperfect-save-gift` or any other donorperfect save or set tool.
* Do not call `business-central-update-journal-line`. A wrong line is fixed by the accountant in Business Central, not by this prompt.

**Validation:**

* If `{from-date}`, `{to-date}` or `{balancing-account-number}` is missing, ask for it.
* Call `business-central-get-account` on `{balancing-account-number}` before Step 4. If no account comes back, ask whether it is a bank account and check with `business-central-get-bank-account` using `bank-account-number`. If neither matches, stop.
* If more than 200 gifts qualify, stage the first 200 by `gift-date`, report the rest as "not staged: run again", and say so in the report.
