n8n ingest swap: lead-intake & onboarding write to the DB

Both flows now POST into the smb-crm DB API instead of appending to Sheets, so
Postgres stays the source of truth and the DB->Sheets mirror keeps the Sheet
current. Telegram notifications unchanged.

- lead-intake: Webhook -> Build lead row -> POST /api/leads -> Telegram
  (dropped the direct Sheets append + the redundant activity-log nodes; the DB
  service logs + mirrors activity itself).
- onboarding: Webhook -> Compute -> POST /api/clients (DB assigns C-id) ->
  Build project w/ returned id -> POST /api/projects -> Telegram. DB computes
  renewal_date; go-live = start + 14d.
- Token injected at deploy time; repo keeps the __CRM_TOKEN__ placeholder.

Verified end-to-end on the live webhooks: lead and client+project land in the
DB and mirror to Sheets; test data cleaned; DB/Sheets consistent.
