When upgrading K values of a LA1.0 print, also adjust E-jerk settings (<2) if permissible according to current accell limits. The same is also true when jerk is set mid-print via 'M205 E'. Existing values are always restored when switching to another compatibility mode. TODO: Since this is stateful, we will need to save the current print mode / acceleration and jerk in the eeprom for this to survive a power panic (see prusa3d#2456)

@gudnimg Aren't these now also stored in eeprom? Please verify. |

We definately don’t save the jerk value. Not sure about acceleration. It is very easy to add this. 👍 |

It looks like we do save the acceleration. But we don't save the maximum jerk value.
We also don't save these values:

Describe the bug
Acceleration and Jerk limits are generally set at the beginning of a print and are usually different to default settings (or eeprom values).
These values currently do not survive a power panic, but they should.
On restart default values are reloaded, which will result in different printing behavior.
