Picks up the three pieces deferred from the initial reports PR:
#3 Line-item account allocation — allocatePoSpend() splits each PO across the
accounting codes its line items carry (line accountId, falling back to the
PO-level account), proportionally so per-PO rows sum back to totalAmount. The
accounting-code report now attributes multi-account POs correctly. SpendRow
gains poId; poCount is now distinct POs, not row count.
#2 Custom "Add to graph" — tick rows on either index (SelectCheckbox links
write ?sel=id1,id2), then "Compare selected" (?cmp=1) shows a custom comparison
of just those entities. Fully server-rendered + shareable; export honours sel.
#1 Weekly granularity — a third Granularity that focuses one FY month and
buckets spend by week-of-month (W1–W5) from approvedAt, with a Month picker in
the toolbar. Real buckets (not the mockup's synthetic split).
All three are URL-driven like the rest, so no client fetching. Charts/KPIs/
detail trends all branch on the new mode.
Tests: +8 unit cases (allocation proportional/fallback/empty, weekly buckets,
sel parse/toggle, month + granularity parsing); fixture updated for poId/week.
Full unit suite 311 green; tsc clean. Smoke-tested weekly + custom-compare +
exports end-to-end (all 200). Docs + wiki updated to mark them implemented.
