Adds a `credentials` entity to the back office (never mirrored to
Sheets, gated by the CRM token even to read) so client logins like
the auto-generated Easy!Appointments provider password can be viewed
and copied from the dashboard instead of getting lost — the actual
cause of the happynails password going missing. Onboarding now saves
that generated password instead of discarding it. Also adds
Documentation.md, brings README/TODO in line with the current
Postgres-first architecture, and tidies the backlog.

Stand up the DB-first CRM backbone (architecture pivot: Postgres is the
source of truth, Google Sheets becomes a one-way downstream mirror).
- backoffice/ stack: smb-db (Postgres 16) + smb-crm (Flask/waitress service).
- Schema mirrors the six Sheet tabs (clients, leads, projects, activity_log,
bookings, invoices) with typed columns + updated_at triggers.
- Service-account Sheets client (PyJWT) for the one-time import + future mirror.
- import_from_sheets.py: idempotent seed of Postgres from the live Sheets.
- Read dashboard (Leads & Clients tables) at onboard.mivanchenko.de/crm,
behind the existing Caddy basic-auth; JSON API reads straight from Postgres.
Deployed + verified: import seeded DB, dashboard/API live, no-auth blocked,
onboarding form unaffected. Add/edit/delete + DB->Sheets sync + n8n ingest
swap are the next steps.
