Changing Proprietor in SP Alteration should only be allowed for change of proprietor by amalgamation

Please refer to OPS ticket - ITOPS-186220 ITOPs REQ / BCROS - FM0493718 - missing information on auto generated document (link TBD).

Problem:
- [ ] Staff only have access to replace a corporation proprietor and add another corporation proprietor.
- [ ] Valid Use case
- The original corporation proprietor amalgamated into another entity
- The new entity took over the firm
[ ] Invalid Use case
- Staff replace a corporation proprietor and add another corporation proprietor, that has no relationship with the original corporation proprietor.
- This would be an invalid filing, and the firm would become an invalid legal record.

Impact:
- [ ] We had so far two such instances where the corporation proprietor was incorrectly changed, and then added back.

Mitigation:
- [ ] We need the filing, as is, for the valid case.
- [ ] We need to prevent the invalid case.

Changes required:
- [ ] Add an acknowledgement and clickable radio button; "This new corporation entered as a proprietor is a result of the amalgamation of the original proprietor, and is legally taking over ownership of this firm" - or something to this extent.

No files, tests, or entry points are identified in the issue. Start by tracing the SP Alteration proprietor replacement flow and how the filing and auto-generated document are produced. Done means the valid amalgamation case remains available while an acknowledgement is required to prevent the described unrelated proprietor replacement.
