feat(sponsor-reports): surface partial line cancellations in the By Item and Lines Manifest views

[caseylocker]

ref: https://app.clickup.com/t/9014802374/86bbpjzmm

Both Purchase Details report views read the binary is_canceled only, so a partially cancelled line rendered as fully live and its cancelled units counted as purchased. The API has returned canceled_quantity, canceled_amount and is_partially_canceled since sponsor-reports-api #41; nothing here consumed them.

What changed

Two pure helpers plus a shared status token, exported from LinesManifestView.js (the one-way ByItemView -> LinesManifestView dependency already existed):

• liveQuantity(row) and liveAmountCents(row) net the cancelled portion, clamped at 0, null-in/null-out for money.
• lineStatus(row) resolves the line's own three-way state, and LineStatusPill renders it. A soft-cancelled or partially cancelled line leaves its parent order Paid, so purchase.status alone printed "Paid" on a row with real cancelled units.

By Item nets both units and money into the item aggregates. The money subtraction is exact rather than prorated: canceled_amount is the source's own frozen sum for the cancelled units, and the source charges partial events at floor unit price, so proration drifts by cents. Drill-down contributors carry the same live money they contribute, so the rows sum to their own header.

Lines Manifest shows the cancelled portion on the row: 3 / 5 units and $1980.00 / $3300.00. Live over charged for money, because that column is the only per-line money surface finance has and netting alone would drop the charged figure.

Deliberate, not oversights

• A fully cancelled contributor keeps its ordered quantity and charged total. The row is struck through; 0 / $0.00 would erase what the cancellation was for. Item aggregates are unaffected either way, since a fully cancelled line never enters the if (!row.is_canceled) block.
• bucketLinesBySponsor is untouched. liveLineCount counts lines, not units, and a partially cancelled line is still one live line to fulfil.
• Active and fully cancelled rows render exactly as before.

Known divergence, tracked in 86bbmwk83

The Total Items tile is computed server side (purchase_details_summary, Sum('quantity') filtered on canceled_at IS NULL) and cannot be corrected from this repo. On dev summit 73 it reads 212 against a netted By Item Σ Qty of 201, a gap of 11. 86bbmwk83 closes it. If that ships in the same release there is no window; if not, the two disagree only on data containing a partially cancelled line.

Verified on dev

Deployment slot 13, backfill run, 8 partially cancelled lines. Every rendered figure was checked against the database:

Order	Item	Qty	Line Total
000051	SJC-GR04	2 / 4	$700.00 / $1400.00
000051	SJC-L-D	2 / 3	$500.00 / $750.00
000051	FN-F04	3 / 5	$1980.00 / $3300.00
000052	SJC-F03	5 / 10	$675.00 / $1350.00
000034	SJC-EL15	1 / 2	$50.00 / $100.00

By Item drill-downs sum to their headers (SJC-L-D: 2+5+2 = 9 units, $500+$1250+$400 = $2150). All five sit under Paid orders, which is the trap this fixes.

yarn test: 183 suites, 1634 tests. eslint clean on the changed files.

Note for review

Partially Canceled and Pending both map to the warning tone, so they share a colour in the Status column. The labels differ and are readable, but they are not separable at a glance, most visibly in a By Item drill-down where the two sit adjacent. secondary is the only unused tone in TONE_BY_STATUS if you would rather they were distinct. Happy either way.

Pull request overview

This pull request updates Sponsor Reports “Purchase Details” views to correctly represent partially canceled line items by netting canceled units/amounts in aggregates and surfacing a distinct per-line status indicator (rather than relying on the parent order status).

Changes:

• Added shared helpers in LinesManifestView.js to compute live (net) quantity/amount and a three-way line status, plus a LineStatusPill renderer.
• Updated By Item to net partially canceled units and cents into item aggregates and to display split quantities and line-level status in drill-down contributors.
• Updated Lines Manifest to display split quantity and “live / charged” money for partially canceled lines, and to render the line-level status pill.
• Added the “Partially Canceled” i18n string, updated status tone mapping, and expanded unit tests to cover the new behavior.
