The resolver only read the self-hosted directory table, which is empty
at sites running the external HR directory - every kiosk badge fell to
the deny policy. It now branches on employee_directory_mode like the
usb plugin: selfhosted looks up DirectoryEmployee by SSO; external
queries the HR directory via employee_connection, resolving PayNo
badges by their real PayNo column and recovering the employee's SSO.
Badge resolver copied from the USB contract (SSO digits, 0<digits>BZ
PayNo wrap) with names from the employees directory and the
unknown-badge policy setting; deliberately copied rather than
cross-imported so the contract test stays green. Restock and adjust
write the ledger row and move the cached quantity in one commit -
the single-commit invariant every write path must use. Adjust
requires a reason and refuses to drive stock below zero. Detail page
gains Restock/Adjust modals. Seven tests cover minting, the
cache==ledger invariant, badge shapes, policy toggle, and auth.
