Redesign "Copy and Edit" modals

### Dependency
- #2332
- We need to decide whether or not the "Copy & Edit" and "Duplicate" functions need to be separate. Using the word "duplicate" in the content of these modals could be beneficial, but not if it's going to cause confusion with the Duplicate function.

### Overview
We need to redesign the three "Copy and Edit" modals to increase clarity to the user and so that they match our style guide.

### Details
Per #1795, there are two workflows that allow a user to copy a snapshot into a draft and subsequently edit that draft.
1. The snapshot's author makes a copy.
2. The recipient of the shared snapshot makes a copy.

The steps for each workflow can be found in the Instructions section below.

In each of the workflows, two modals appear.

Modals if author copies


Modals if recipient copies


Please redesign the modals so that they match TDM style guidelines and help the user to complete their intended task.

### Instructions
See [this comment from 1795](https://github.com/hackforla/tdm-calculator/issues/1795#issuecomment-2726144004) for a video of these workflows.

Start with the existing Copy and Edit workflows on the TDM Dev site, the original design workflow in Figma, and the video linked from issue #1795. Review the three modals against the TDM style guidelines and the dependency in #2332. Done means approved Figma designs, updated design-system references, stakeholder sign-off, and a development handoff issue.
