Earthshaper becomes Technomancer by installing Crystallized Mana Nose CBM

[wapcaplet]

Describe the bug

When a character has the Earthshaper trait (and is locked out of the Technomancer class), they can become a Technomancer simply by installing the Crystallized Mana Nose CBM.

Steps To Reproduce

1. Learn an Earthshaper spell, and accept the prompt to become locked out of Technomancer class
2. Get a Crystallized Mana Nose CBM and some anesthetic
3. Find or map-edit in an Autodoc and couch
4. Use the autodoc to install the CBM, and accept the prompt to lose the Earthshaper trait

Expected behavior

Converting from Earthshaper to Technomancer should not be possible.

If the character has the Earthshaper class already, they should not be able to attempt a Technomancer CBM installation at all.

Screenshots

Prompt warns that Earthshaper trait will be removed, but no mention that Technomancer will be forced upon them:

#47822 probably does what this wants.

Can this be closed or does someone need to make some changes using json from #47822 to finalize this?

Stil reproducible. Changing "canceled_mutations" to "mutation_conflicts" for the CBM, per the linked PR, does prevent installing the Nose CBM:
