- remove undocumented spec.kiali_feature_flags.ui_defaults.mesh.impl
- remove now-unused /api/clusters API

…ace behavior

- Add in the actual "Mesh" tour stop

infra...

- note that '/api/mesh/ API is also only used in tests, but there
  is a decent amount of infra around that testing, and it does test
  the same core code as is used in the mesh graph gen, so I'm leaving
  it in place.

- expose PFT Controller in MeshPage state
  - note: not sure we can get state for Hooks, only classic classes, so
    using MeshPageComponent as opposed to MeshComponent.
- start adding a few basic tests

- note that the expected result is actually wrong due to a bug, will
  be fixed shortly via Fernando's PR, and the expected result will be
  updated.

- More basic cypress tests

- add icon on DataPlane node.
  - small refactor from if-then to switch stmt

… and

to hopefully work both locally and in CI.

…some

unused definitions.

issue with DataPlane nodes for canary versions, and possibly other
situations.

- fix double-revision in istiod name
- add I18N to UNKNOWN constant, and use as opposed to literal
- mesh side panel
  - for clarity, increase indent on infra
  - for conciseness, remove namespace for non-istiod
  - sort infra, and move istiod(s) to top

  - remove the "no canary" test from overview, it's irrelevant
- add a missing @sleep-app to an overview test

- Add version info for grafana via API, if possible
  - note that tracing version may be unavailable via api, or may need a different approach

- reduce whitespace for dataplane namespace, when it lacks chart metrics
