Add member profile questions, admin tooling, legal pages, and fast tests

- Add configurable profile questions with conditional visibility, admin-only fields, user answers, and seeded onboarding/volunteer questions
  - Add admin UI for managing profile questions and member profile answers
  - Add volunteer level/profile data support across backend schemas, models, API, and migration
  - Update dashboard/profile UI, super admin menu, membership service types, and related styling
  - Add privacy policy, terms of service, cookie notice, and footer links
  - Add frontend Vitest coverage for profile question logic
  - Add backend pytest coverage for profile answer normalization and validation
  - Update restart.sh to build, run frontend/backend unit tests, and restart only after tests pass
  - Refresh README, quickstart, project structure, instructions, and Square docs to match current app features
    - Protect feature flag reload behind super-admin access
    - Restrict admin-triggered password resets so admins can only reset member accounts
    - Replace email template HTML preview rendering with escaped text preview
    - Update docs for feature flag reload access, password reset scope, and email template preview safety

    -- test user questions are also made by AI and not very useful. but i didn't know what to put there so its good enough for a test
