crtc: remove Canadian accountant/accounting-setup service (no longer offered)

We no longer offer Canadian accountant/accounting setup. Removed all
service-offering content:
- Marketing page (services/telecom/canada-crtc): the 'Set Up Canadian
  Accounting (we help)' next-steps card, the '3 hours of complimentary
  accounting consultation' deliverable bullet, and the whole 'Accounting
  Support' section (assigned accountant, portal chat, $75/hr, 3 complimentary
  hours).
- Order page (order/canada-crtc): the '3 hrs Canadian accounting support'
  included-feature bullet and the 'Preferred accounting software'
  (Xero/QuickBooks) form field + its accounting-hours helper text.
- Fulfillment (canada_crtc.py): dropped the bank-setup email line offering
  '3 hours of Canadian accounting consultation'.

Kept factual GST/HST tax advisories and the bank's QuickBooks/Xero
transaction-sync feature (third-party bank capability, not our service).
