Builds the referee workflow end to end: club-defined RefereeLevel/RefereeProfile eligibility tied to teams, EventReferee assignment (member or external, with fee/km payment tracking), an admin dashboard with KPI tiles, date-grouped game tiles and range filters, and a downloadable payment form PDF modeled on the club's existing paper document (using Club.legal_name when set). Also lands team roster bulk-add, member mass-upload with family linking, and the members.Group model, developed alongside this work. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

"""HTML-to-PDF rendering for exports (currently just the memberships list).
|
|
|
|
Same lazy-import shape as billing.services.invoices.render_pdf -- WeasyPrint binds
|
|
to native pango/cairo libraries, and a machine without them must still be able to
|
|
run the app, the tests and every other page, so the import happens here, not at
|
|
module scope, and only fails when someone actually asks for a PDF. Kept separate
|
|
from billing's version rather than shared: the two exports have nothing else in
|
|
common, and sharing would make one app depend on the other's error type for no
|
|
real benefit.
