C2MS12 — Create final version of all model diagrams that have more than one resolution

Some model diagrams are affected by more than one issue, and as such, all the changes need to be combined into one final SVG image in this issue to finalize the edits.

Note, for example, that some messages (see Event and Log Message from C2MS12-43) have a 2025 date, but should be made 2026, because 1.2 has taken a bit longer than planned and will be finalized in 2026. It would be good to go through every model change and determine for sure if it needs to be content-version of 2026.

Also, note that in C2MS12-53, all message diagrams are being updated, so really, this issue should capture all the final changes. Because of the same issue, all messages should have a CONTENT-VERSION of 2026 because of the addition of CUSTOM-FIELDs.
