Improved E2E fixtures with reusable role auth state

[jonatansberg]

ref https://linear.app/ghost/issue/BER-3366/rework-e2e-fixtures

What changed

• Reworked global setup to create and reuse a local fixture package (DB snapshot + per-role auth states)
• Added role-aware Playwright auth context helper and role fixture support
• Added staff invite + role onboarding setup flow for owner/administrator/editor/author/contributor
• Added fixture cache invalidation checks (missing files/migration mismatch/forced reset)
• Updated dev/build gateway Caddy config to rewrite Origin consistently for admin/API traffic

Notes

• This branch is rebased on ber-3363-unified-environment-manager
• Local override env var is E2E_FORCE_FIXTURE_RESET=1

Validation

• yarn workspace @tryghost/e2e test:types
• yarn workspace @tryghost/e2e lint
• Focused and full Playwright runs executed in dev mode to inventory failures
