Add support for Visible History to time series space views #4179

What

Add support for Visible History to Timeseries space views
- Needed to introduce DataStore::entity_min_time() to maintain the consistent "beginning of x axis" behaviour.
Changes the way the Visible History feature is organised:
- Now all space view (blueprint) contain a "root entity properties" structure that is cascaded to the enclosed groups and entities.
- The visible history part of that root entity props is editable for all supported space view classes (now 2d, 3d, and timeseries).
- The rest is unchanged: this means that contrary to the plan it's also possible to edit the visible history on a per-entity basis in timeseries space views as well.
Closes Allow to set a sliding window for time series plots (aka support the Visible History feature) #2547

Follow-up TODO (before 0.11)

Known limitations

default value for EntityProperty is not ideal for entities in timeseries space view (2x Relative(0))
Add support to skip the "latest_at" semantics with range queries #4192

TODO

freeze the plot display bounds while the time cursor is dragged
setting must be serialised to blueprint

I don't really get why we would have a toggle for "Visual History". Shouldn't we just pre-fill the options that correspond to the default behavior for all the views? Then we can just make it editable for the views / data that support it.

For instance if we can't support visual history, we would just set the range to 0, 0 and have it not be editable. The time series plots would default to -♾️,+♾️

Fwiw, I think renaming this to something like "Included time range" or "visible time range" would make it more clear but I won't die on that hill.

… to use this instead of the ad hoc state in the timeseries space view.

I think something like this would be easier to understand:

I don't really get why we would have a toggle for "Visual History".

Two motivations I can think of:

Disabling the feature would be, in general, cumbersome (2x set to "Relative" and enter "0").
Make the cascading behaviour explicit. Now a child will override the parent (group, space view) if its Visible History is enabled (regardless of actual settings). If we remove that, then the cascading logic becomes much less obvious.

I think something like this would be easier to understand

I like the reordering of controls. I'm not sure about merging the concepts of "infinite" with "absolute". "First + 10s" feels less useful than "t = 63s" (assuming the timelines first logged data would be at 53s, which could be accidental).

- keep plot bounds from changing while the time cursor is dragged - correct min time computation - don't draw the time cursor out of the plot area

@teh-cmc I think this doesn't respect your prescription of using only stuff from re_log_types::example_components or re_types_core, but it's done all over the place in this file already 🤷🏻

Mistakes were made in the past, let's not repeat them 🙃

Done 👍🏻

Played around with it a bit and it works great!

Please remove the use of positions and colors from the store tests before merging.

Why rename here? The previous one was better imo.

~~Yeah I went back and forth with these and this one clear got forgotten.~~

Edit: actually no, space_view_class was used everywhere in this file before, I just made this one consistent. This naming choice (which also wasn't my preferred) wins by 42 to 15 throughout the codebase, so best keep it that way for now imo.
