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

[abey79]

What

• Part of: Dataframe view: add PoV to range query #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 New ChunkStore APIs to facilitate data access #7284).
• Ignore the ugly "Time range table order" part, this will be cleaned up later (Dataframe view: sorting and primary column selection #7070)

The "Time range table order" has more indentation than the rest

The "Time range table order" has more indentation than the rest

I'm gonna let that one slide. I don't have control on that bit of UI (auto-derived from blueprint archetype), and it's going away anyways:
