Add point-of-view entity and component to the dataframe view's UI (#7331

)

### What

- Part of: #7279

This PR updates the dataframe query override UI as per design in #7279,
in particular adding PoV entity and component.
- updated UI layout
- time boundaries default to `+∞`/`–∞` button which, when clicked, turn
into editable time drag value
- reset buttons to go back to the `∞` state
- auto-selection of PoV component based on PoV entity (picks a required
component for one of the entity archetypes)

**Note**:
- This is a pure UI PR. The PoV entity/component are not yet used at all
for the dataframe's content (that will be addressed in a follow-up PR
currently blocked on #7284).
- Ignore the ugly "Time range table order" part, this will be cleaned up
later (#7070)
