alerts: Teams webhook fan-out (contract 0.14.0) + printedparts detail revision column

send_webhook(title,text) posts alerts to an optional webhook (Teams Incoming
Webhook / Workflow, or generic JSON) via alert_webhook_url + alert_webhook_format
settings; send_alert fans out to it alongside email; exposed on shopdb.api
(0.13.0->0.14.0, PLUGIN-HOOKS synced); low-stock posts on its custom-recipient
path too. Also: recent-transactions table shows the consumed print-file revision.
