Extends stock event.registration with a signed QR ticket system, built to
complement rather than duplicate Odoo 19's existing barcode/badge
infrastructure. ticket_ref ('TIX-{event}-{seq}') and a QR code encoding
"ticket_ref|hmac_token" are added; the HMAC is signed with Odoo's own
per-database secret (ir.config_parameter 'database.secret', the same
mechanism core uses for password-reset tokens), so a copied/edited
ticket_ref without the matching signature is rejected as forged. A "Event
Ticket (QR)" PDF report is auto-attached to the core registration
confirmation email by adding it to event.event_subscription's
report_template_ids - no override of core mail-sending logic needed.
Adds the missing piece core doesn't provide: a mobile-friendly staff
check-in page at /event/checkin (gated on event.group_event_registration_desk),
built as a v19 "Interaction" (registry.category("public.interactions"),
the current replacement for legacy publicWidget) with manual ticket-ref
entry always available and camera scanning via the browser's native
BarcodeDetector API - avoiding a third-party CDN dependency and its
security/offline-reliability tradeoffs. Guards against forged tokens and
double check-in; a live per-event registered-vs-checked-in dashboard.
Two more real Odoo 19 surprises hit here: event.event has no more `state`
field at all (replaced by a stage_id/event.stage kanban system - my
check-in page's event picker now filters by date_end instead), and a
route type='json' should be type='jsonrpc' (json still works but is
deprecated).
Verified against a live Odoo 19 + Postgres 16 container: 9/9 tests pass
(ticket generation/uniqueness, valid/duplicate/forged/tampered token
handling, manual lookup), plus a full manual live run over HTTP - created
an event and registration via JSON-RPC, confirmed ticket_ref generation,
authenticated a session, hit /event/checkin/scan for a real check-in and
duplicate rejection, confirmed dashboard counts update, and loaded the
actual /event/checkin page (title, camera-button markup, and our JS
present in the served frontend bundle).
