ui: add parameterized dispatch interface (#10675)
* ui: add parameterized dispatch interface

This commit adds a new interface for dispatching parameteried jobs, if
the user has the right permissions. The UI can be accessed by viewing a
parameterized job and clicking on the "Dispatch Job" button located in
the "Job Launches" section.

* fix failing lint test

* clean up dispatch and remove meta

This commit cleans up a few things that had typos and
inconsistent naming. In line with this, the custom
`meta` view was removed in favor of using the
included `AttributesTable`.

* ui: encode dispatch job payload and start adding tests

* ui: remove unused test imports

* ui: redesign job dispatch form

* ui: initial acceptance tests for dispatch job

* ui: generate parameterized job children with correct id format

* ui: fix job dispatch breadcrumb link

* ui: refactor job dispatch component into glimmer component and add form validation

* ui: remove unused CSS class

* ui: align job dispatch button

* ui: handle namespace-specific requests on job dispatch

* ui: rename payloadMissing to payloadHasError

* ui: don't re-fetch job spec on dispatch job

* ui: keep overview tab selected on job dispatch page

* ui: fix task and task-group linting

* ui: URL encode job id on dispatch job tests

* ui: fix error when job meta is null

* ui: handle job dispatch from adapter

* ui: add more tests for dispatch job page

* ui: add "job dispatch" capability check

* ui: update job dispatch from code review
