fix(exam): allow any institute teacher to fetch template source PDF

Removed the teacher_id ownership check from _require_source_visibility_or_404.
RLS already ensures a teacher can only see templates in their institute;
the ownership gate was blocking shared templates (e.g. board-uploaded AQA papers)
for any teacher who didn't personally create them.

+"""Project a saved exam template into the cc.public.exams Neo4j graph (card S4-7).

+ExamPaper → Question/Part → Region, plus Part-[:ASSESSES]->SpecPoint — is projected here.
+
+Ownership model (R3.5.1): the graph is written by the API SERVICE ROLE only (no client writes),

+Projection is a full re-sync per exam_code (delete this paper's Question/Part/Region, recreate),

+"""Marking batches, scans, marks, results & CSV (/api/exam/batches..., /api/exam/marks/...) — S4-6.

+As with templates, all user-facing access is as-the-user (RLS-enforced; E1). A batch is owned by
+the teacher who creates it (R2.4); colleagues in the same institute can read it
+(marking_batches_read), a teacher in another institute cannot (→ 404, IDOR-safe).
+
+Roster→cohort (R4.3/A7): creating a batch from a class materialises one student_submissions row
+per active enrollee (status='absent'), so every enrolled student is present in results/CSV from
+the start and a no-show is never silently dropped. The roster ids are read AS THE USER from
+class_students (cs_read requires the caller to teach/admin the class); only the display names are
+resolved via service role (profiles is deny-all as-user, E4 — see resolve_student_names).
+
+Scans (R2.3/E3): the upload endpoint enforces a max size and validates that the bytes are a PDF
+before storing. QR-decode + automatic student-matching is a follow-on (no QR'd fixtures exist
+until the PrintGenerator card); v1 supports explicit (manual) and ordered matching.

+seed_cohort_9p_ph1.py — Markable cohort for exam-marker testing.
+
+Creates N student accounts and enrols them ALL into a single class (default the
+Greenfield Year 9 Physics class `9P/Ph1`), so there is a real cohort to mark.
+
+Why: the canonical timetable seeds enrol "one student per year-group band"
+(seed_greenfield_timetable.py), so every class has <=1 student — too few for a
+results table / per-question stats. This seeder fills one class to a usable size.
+
+Mechanics (identical paths to the canonical seeds — nothing bespoke server-side):
+  - auth user:   POST {SUPABASE_URL}/auth/v1/admin/users
+  - profile:     upsert public.profiles  (school_id = institute)
+  - membership:  upsert public.institute_memberships  (role 'student')
+  - enrolment:   POST {API_BASE_URL}/database/timetable/classes/{class_id}/students
+                 (as a school_admin; class_students upsert → idempotent)
+
+Idempotent: re-running skips existing auth users and upserts everything else.
+
+Env required:  SUPABASE_URL, SERVICE_ROLE_KEY   (API_BASE_URL defaults to api-dev)

+seed_kevlarai_timetable.py — Full timetable + class + student seed for KevlarAI school.
+
+Mirrors Greenfield's structure so both schools are testable.
+KevlarAI gets 8 classes across 3 subjects (Physics, Maths, Computer Science),
+2 teachers, and 2 students.
+
+Flow:
+   1. POST /timetable/setup              — academic year, 3 terms, periods → Supabase
+   2. POST /timetable/materialize-periods — academic_periods rows (days x template)
+   3. Create classes                     — 8 classes with correct metadata
+   4. Add teachers to classes            — primary teacher per class
+   5. POST /timetable/init + slots       — TeacherTimetable + slot assignments
+   6. Patch slot class_ids               — write class_id FK onto teacher_timetable_slots
+   7. Enroll students in classes         — student1→Yr10, student2→Yr11
+   8. POST /timetable/materialize        — taught_lessons with class_id populated
