Adding account creation details to companies Annual Report reminders coming out from COLIN

AS an end-user
WHEN I receive an Annual Report reminder coming out of COLIN
THEN the reminder will contain instructions on how to create an account on BCROS
AND I would be able to pro-actively create a BCROS account in preparation for COLIN Phase I go-live

**General To Do List** - to be refined:
- [ ] Design the message - OCM
- [ ] Update the COLIN companies Annual Report reminder text - Home Teams - BA's, Developers
- [ ] Test and Deploy updated AR messages to Prod - Home Teams - BA's, Developers
- [ ] Design and implement a progress tracking mechanism - OCM, Relationships Team
- [ ] Design and implement a related customer support process - OCM, IT Ops, Relationships

No files, tests, or entry points are identified; start by locating the COLIN Annual Report reminder implementation and the BCROS account-creation wording. Done means the reminder contains account-creation instructions, progress tracking and customer support processes are defined and implemented, and the updated messages are tested and deployed to production.
