Gives clubs a self-service /manage/ area for members, families, teams, roles, and season memberships, alongside real fee-payment tracking (FeePayment, record_payment/mark_as_paid/remaining_balance) so a membership's paid status reflects actual money received instead of a single manually-set flag.

"""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.
