feat(crm): client-meeting batch — contact-pill cleanup, assignment toggle, receipt manual mode

CM-4: remove Email/Call/WhatsApp deep-link pills from the client + interest
  detail headers; relocate GDPR export into the client-header action cluster
  as a compact icon. Keeps the interest "Log contact" quick action.
CM-5: gate the interest assignment feature behind a per-port `assignment_enabled`
  setting (default OFF for single-rep ports). Hides the AssignedToChip +
  residential assigned-to row and skips tier-2/3 auto-assign on create; the
  column + data are preserved and reversible. Tests cover the auto-assign guard.
CM-6: add a per-port `manualEntry` receipt mode (skip all parsing → empty form).
  Threaded through ocr-config.service, the admin OCR form, the scan-receipt
  route, and the scanner shell (skips Tesseract + the server call). Tests cover
  the save/resolve round-trip.

Verified: tsc clean, lint 0 errors, 1631 vitest pass, prod build green.
