feat(forms): obvious publish flow, member Forms surface, templates (P8)

- builder: draft/published/closed status banners; creating a form now
  lands on its edit page so Publish is immediately visible; a
  members-only form shows a "no public link" note instead of a dead URL
- member-facing forms: /my-forms list + /my-forms/[id] fill
  (MemberFillClient), "Forms" sidebar item for all members. Fixes the
  long-standing gap where members-only forms had no fill surface
- starter templates: lib/form-templates.ts + a picker on /forms/new
  (Liability waiver, Membership application, Event RSVP, Photo release,
  Blank) that seeds builder state (no table)
- forms-client relabels members-only forms (was showing a misleading
  /f/<space>/<slug> that always 404s for members-only)
- docs corrected per the audit pass: DATABASE_SCHEMA / DB_SCHEMA_MAP /
  ARCHITECTURE / API_REFERENCE now reflect migrations 014-029, per-space
  slug, /f/[space]/[slug], getPublicForm({space,slug}), invite roles;
  HANDOFF pass-19 added with residual gaps
