Add epoch information and slider in all run specific tables as well as all explorer pages (wherever step slider is available or step information is available)

🚀 Feature

I have a general request on top of this issue (https://github.com/aimhubio/aim/issues/1519), for example in the texts and figure tab - I was seeing a toggle for steps but not epochs. Is there any reason behind that? Many of the explorers and other run specific tables also don't show epoch specific information to my surprise, I'm not sure why.

Pitch

In general epoch slider (along with the current steps slider) must be shown on all pages wherever possible ideally - the reasoning behind this is that steps are associated to mini-batches which in most cases isn't useful. But epochs denote which stage of the training it was logged in, which is far more useful to see as a user. (That being said steps slider must also be there, but epoch slider/information must be also rendered across pages).

And once the epoch information is shown, the default should be to set to show "last epoch" in all such explorer pages and run-specific tabs (figures/audio/image/text etc) IMHO. Can this be please done for?

See: https://github.com/aimhubio/aim/issues/1519 for more context.

Motivation

Epoch information/slider must be present in all run specific tables as well as all explorer pages wherever step toggles are present/step information is present.
