[BUG]: The "Transitions" table in the model page are missing the rate laws and have other issues

[liunelson]

Describe the bug

Issues:

• the Transitions table in the model page used to show the rate law that is associated with each transition/template. These rate laws are now missing. They should be shown in a code font (since the rate laws are SymPy expressions).
• I have no idea what the purpose of the template-, template- on each row. What should shown as the first, bolded entry of each row should be just the model.transitions[].id of each transition/template in the model AMR object. The editable text field should be model.transitions[].properties.name.
• Model transitions/Templates have no 'unit' property in general and the 'Unit' field should be removed from the table.
