[CRO] Fix for data layer: deviсe and account type data is null, minifying page and identify events for rudderstack, add country and language context for growthbook

[NikitK-deriv]

Changes:

As a developer and analyst I want see only proper and clear data in database, also I want to prevent extra page and identify calls when it's unnecessary.
To reach the first value we have to refactor existing setup and be sure that we send only data, without null and undefined properties. Also to reach the second value, we have to minify event calls and set them only when needed from business perspective (i.e. user authorised, change wallet, etc.)

Screenshots:

Should provide all data on each track event, without nulls and undefined:

Page event should call on each route change:

experiment_view event aka a/b testing feature appeared should pass directly to google analytics:
