feat(classes): schema + RLS + permissions (data layer)

Browse Source 
Migration 032 adds classes (offering; optional payment_link and
grants_certification_id, is_active archive), class_sessions (scheduled
occurrence; denormalized space_id) and class_signups (member signup;
partial unique = one non-cancelled signup per member+session). RLS is
additive and default-deny: classes readable by managers (all) or members
(active only), class_sessions by any space member, class_signups by
managers/instructors (all) or the member (own) with instructor-only
UPDATE and no INSERT/DELETE policy so signup/cancel funnels through a
validated service-client action (capacity/waitlist/dedupe). New
classes.manage + classes.instruct permissions (group Classes) seeded to
board and backfilled. Mirrored idempotently in schema.sql; types and
schema docs updated.

`scripts/schema.sql` is the canonical idempotent schema; each numbered
migration is mirrored as a section in it. Tables/columns added:

| 029 | `space_invites.role` (member_role enum, default `member`) so an invite can grant a chosen role; legacy invites and the spaces.invite_code path keep granting `member`. Who may create an admin-granting invite is enforced in-app (only an admin) |
| 030 | `certifications` (per-space cert types; optional `validity_months`; `is_active` archive) + `member_certifications` (per-member grants; `expires_at` snapshotted at grant time; soft `revoked_at`/`revoked_by`; partial unique on one active grant per member+cert). RLS additive + default-deny: certifications SELECT = any space member, write = `certifications.manage`; member_certifications SELECT = `certifications.manage`/`certifications.grant` (all) or member (own), INSERT/UPDATE = `certifications.grant`, NO DELETE policy (history immutable). New `certifications.manage` + `certifications.grant` permissions (the latter = the Instructor capability) seeded to board + backfilled. No anonymous path |
| 031 | `secrets_select` additively also honors the `ops.secrets.read` role permission (was admin/board OR per-secret `ops_acl` only; the permission was never consulted). Access-neutral unless an admin has granted the permission. Reveal/list server-side gates updated to let RLS be the boundary; write paths unchanged |
