Implement /cases/edit so it goes into edit

[AdamFinkle]

We want a screen accessed by /cases/edit where we can update a record.

• Create a state variable , called caseId (look for useState in Single.tsx)

[ZaimaGull]

• Display caseId
• Removed feature flag

*** Update living area ***

• Pass analysis.id to action
  • Someday consider rename HomeSchema?
  • Modify zod HomeSchema schema to include analysis.id
  • Make all the changes you need to make to pass analysis.id to action. Namely, make other changes to include analysis.id when submitting. Tip: look for living_area in heat-stack directory and where appropriate, do something similar for analysis.id. There should be an input field called home_id which is set to home.id.
  • Modify action to console.log the analysis.id of the case to prove that you have successfully passed the analysis.id to action.

---

If home.id is undefined
    create data  // because we don't want to create data when updating.
else update home
   prisma.home.update({
       where: { id: home_id },
       data {
           living_area
       },

Background
For Homeowner and Location, there will only be a single case

• For v1, editing a case will result in editing the associated analysis rather than creating a new one
  -- n.b. there is a foreign key relationship between analysis and case.
• For later versions, there could be multiple analyses for a home, based on changes to the input calculation, new calculation algorithm, etc.

Although there are multiple tables, when the form submits, action creates a new record for analysis, heatingInput, case, and location, and these new records will be associated with each other in version 1.0. When you update the case on the screen, the associated records for the case should be updated. There will only be one analysis, one heating input, and one location per case.

Goal: When you add a field to epic stack object/table, you need to include the new field in multiple different source code files.

Consider using relevant Prisma techniques to update multiple linked tables at one time to save effort/lines of code:
