Users: employeeId auto-generated from role prefix (TCH/MAN/ACC/MGR/SUP/AUD/ADM)
followed by next sequential number; shown read-only in edit form, removed
from create form. Cost Centres: new code field (SITE-001 ...) added to
Vessel model with migration + backfill; auto-generated on create, read-only
in edit. Vendors and Accounts: code/vendorId inputs pre-filled with the
next suggested ID (VND-001, ACC-001) from the server page; user can override
with any PREFIX-NUMBER format, validated by regex.

Allow accounts to record partial/advance payments against a PO before
full delivery. A new PARTIALLY_PAID status tracks in-progress payment;
paidAmount accumulates across multiple markPaid calls. PO only closes
when both paidAmount >= totalAmount AND all line items are delivered.

PO_SUBMITTED: managers only, submitter no longer copied
PAYMENT_SENT: submitter only (it is a receipt prompt, not a manager action)
PARTIAL_RECEIPT_CONFIRMED: managers now notified via new event type
RECEIPT_CONFIRMED: unchanged (managers + accounts)

Subject line now reads 'Purchase Order XXXX' instead of 'PO XXXX'.
Each email includes a recipient-specific deep-link action button,
a PO summary card (number, title, submitter, vendor, vessel, cost centre, total),
and a line items table with qty/unit price/GST/line total.
notify() fetches enriched data internally so no call sites change.
