Generic form system: GraphQL query side (PR 2/5)

[marcoacierno]

Summary

Second PR of the generic form system stack (stacked on #4705 — review that first). Read-only GraphQL surface for conference forms:

• conference.form(purpose: FormPurpose) → Form | null, mirroring the existing deadline(type) pattern
• Form { id, name, questions } with questions active-only, ordered by order
• FormQuestion { id, label, description, questionType, required, maxLength, options { id, label } }
• Enums exposed as FormPurpose / FormQuestionType (explicit names to keep the schema namespace clean)

Additive schema change only — no mutations, no existing types touched beyond the new Conference.form field.

Test plan

• 7 API tests (api/generic_forms/tests/): null when unconfigured / wrong purpose / other conference; full field shape; options exposure; ordering; inactive questions hidden
• Full suite green (1197 passed); ruff + format clean

Stack: PR1 #4705 → PR2 (this) → PR3 grants backend → PR4 admin display/export → PR5 frontend.

Summary: Adds a read-only conference.form(purpose) GraphQL query exposing generic forms and their active, ordered questions (with select options), stacked on PR #4705's models.

No significant issues found. One thing worth confirming with the author:

• backend/api/conferences/types.py: self.forms.filter(purpose=purpose).first() assumes a single form per (conference, purpose). That's enforced by the model's unique constraint for every purpose except generic (generic_forms/models.py Meta.constraints), which explicitly allows multiple generic forms per conference. For purpose=GENERIC this silently returns only the oldest form (lowest pk) and drops the rest with no way for a client to know more exist. If multiple generic forms per conference is an intentional, supported case, the query-side API should account for it (e.g. return a list, or document that only one is queryable via this field).
