UI: Add ability to search for Evaluations in index

### Proposal

As a follow up to the [Evaluations Index](https://github.com/hashicorp/nomad/issues/11122) we should also include the ability to search for evaluations.

A user should be able to search for evaluations by:
* ID
* Node ID
* JobID
* Previous, Next, and Blocked Eval ID

### Use-cases

This would allow a user to more easily consume the evaluations index without having to manually scan through results.

### Attempted Solutions

This can be done via the CLI with (rather complex) filtering (likely with jq).

Start by reading the linked Evaluations Index issue and the existing evaluations index entry point; compare its fields with the CLI filtering approach using jq. Done means the UI can search evaluations by ID, node ID, JobID, and Previous, Next, or Blocked Eval ID.
