Add project search field to Project Health Dashboard Metrics page

**Is your feature request related to a problem? Please describe.**
The Project Health Metrics page currently shows projects only through pagination. When there are many projects, it becomes difficult to find a specific one.

For example, if someone wants to check the metrics for OWASP Nest or OWASP CRS, they have to go through multiple pages and manually scan the list. This makes the dashboard inconvenient to use.

**Describe the solution you'd like**
Add a search field on the Project Health Metrics page so users can search projects by name.
This search can be implemented in the same way it is already done on the `/projects` page.

**Are you going to work on implementing this?**
- [x] Yes
- [ ] No

**Additional context**
As the number of OWASP projects keeps growing, having a search option will make this dashboard user convenient
