COOPS-UI: should use runtime-only build

## Description:
The coops-ui web app uses the Vue compiler build. However, using the Vue runtime-only build, which is roughly 30% lighter-weight, would save program data needed to run the app and therefore load times.

Ref: https://vuejs.org/v2/guide/installation.html#Runtime-Compiler-vs-Runtime-only

**Dependencies**
None.

**Acceptance Criteria**
The web app must continue to load normally.
The load performance (as measured by Chrome Lighthouse audit) should show an improvement.

**Validation Rules**
None.

Ready to Build (DoR):
- [ ] Stakeholders have approved
- [ ] User story completed
- [ ] What are the dependencies
- [ ] Validation rules defined (UI, Data, Role-Action)
- [ ] Is a formal UAT required

Acceptance / DoD:
- [ ] Design / Solution accepted by Product Owner
- [ ] Acceptance criteria has been defined (happy path, known sad paths)
- [ ] Test coverage acceptable
- [ ] Peer Reviewed
- [ ] Accessibility reviewed and acceptable [checklist](https://github.com/bcgov/entity/docs/coding-standards/accessibility.md)
- [ ] UX Approved
- [ ] PR Accepted
- [ ] Production burn in completed

Start by locating the coops-ui build configuration and identifying where the Vue compiler build is selected. Run a Chrome Lighthouse audit before changing the build, then switch to the runtime-only build and verify that the web app still loads normally and that load performance improves.
