Add explicit permissions for editing fire starts

[andrea-williams]

As an RWCO/ZWCO/maybe forecaster I want To be able to edit the predicted fire starts for a planning area So That I can complete a prep sheet for my planning area/fire centre.

As an non-RWCO/ZWCO I want To be able to view a prep sheet, including predicted fire starts So That I can know how bad things are going to be in my area/fire centre, but I should not be able to edit the fire starts because I cannot be trusted.

Additional Context

• Keycloak docs: https://www.keycloak.org/docs/latest/server_admin/#con-client-roles_server_administration_guide
• it's probably best to start on the backend of this ticket first
• See keycloak spike documentation: https://bcgov.sharepoint.com/:w:/t/01324/EV1OOXcFlkpDokbe3s2eH5oBCROLaZTe4F2UWoy-ztbvQQ?e=kaQ2tg

Acceptance Criteria

• Given I am logged in as some user with {fire starts edit} rights, When I navigate to a fire centre in HFI Calc, Then the fire starts values for each planning area appear as a dropdown, and I am able to change the selected fire starts value, and my change should persist for all future users.
• Given I am logged in as some user WITHOUT {fire starts edit} rights, When I navigate to a fire centre in HFI Calc, Then the fire starts values for each planning area appear as a non-editable text field (NOT a dropdown).
• Given I am logged in as some user WITHOUT {fire starts edit} rights, When I try to hack the system by modifying the network request to a POST request with a modified fire starts value for a planning area, Then the POST request fails and my attempted changes are not persisted.
• There exist unit tests covering all of the above AC.
• Permissions are set up for users as specified by Dana's spreadsheet

Definition of Done

• Does what I have made have appropriate test coverage?
• Documentation and/or scientific documentation exists and can be found

Note: it is exclusively Plans in KFC who are changing fire starts. They export the PDF and share it with R/ZWCOs. If changes are needed, Plans makes the changes and re-distributes the PDF. (UXR session finding)
