A few connected fixes around the invite UI shipped in 81d61aa:
1. **Bug in 81d61aa**: `auth.js` referenced `erpFetch` without importing
it, so every invite returned `erpnext.ok=false` with the silent
"erpFetch is not defined" error in the catch. Imported it from
./helpers alongside the other helpers we already used.
2. **Authentik recovery flow not configured** (caught while smoke-testing):
the brand `auth.targo.ca` has `flow_recovery=None` and no SMTP, so
`POST /core/users/{pk}/recovery_email/` returned 400 "No recovery
flow set." Rather than build out a full Authentik recovery flow
via API (multiple stages, brand patch, SMTP env var changes), the
hub now generates a strong-but-readable temp password
(`X7K2-9NQB-4GHM-3RTW` style — no look-alike chars), POSTs it via
`/core/users/{pk}/set_password/`, and emails it via the existing
Mailjet SMTP (already wired into lib/email.js for invoice sends).
Returns `{temp_password, password_set, email_sent}` so the admin
has a fallback if Mailjet drops the message.
3. **Settings dialog** now shows a credentials panel after submit:
• Green banner "✓ Courriel envoyé" when email_sent=true
• Yellow "⚠ transmettez manuellement" when email_sent=false
• The temp password as a copyable field either way
• ERPNext User creation status
4. **Dev onboarding**: added `apps/ops/.env.example`,
`services/targo-hub/.env.example`, and a top-level `docs/SETUP.md`
that explains the local-dev flow (clone → cp .env.example .env →
npm install → npx quasar dev). The example envs are commented
per-section so a new dev knows which keys correspond to which
external integration. None of the real secrets are checked in —
the .gitignore already covers .env files.
