Fix multi-tenancy/integrity bugs in the models: Form.slug and Field.key
were globally unique (unique=True), so two clubs couldn't reuse a form
slug and two forms couldn't reuse a field key — make slug unique per club
(constraint already present) and key unique per form. Add a
(submission, field) uniqueness constraint on Answer.
Register all four models in the admin (Field inline on Form, Answer inline
on Submission) and add formbuilder to the admin registration smoke test.
Add a service layer:
- submit_form(form, member, data): enforces is_active / login_required /
open window / max_submissions, validates required + choice fields, and
writes a Submission with Answers atomically (FormSubmissionError carries
per-field errors).
- build_form(form): a live django.forms.Form built from a Form's active
fields, mapping each FieldType to the matching form field.
- form_report(form): a tabular overview of every submission's answers plus
per-value tallies for choice-type fields.
Full suite at 100% coverage.
