housekeeping: factor out components for easier BaseLayout reuse (#4604)

* improve: wrap schemes to encapsulate rendering logic
* improve: wrap filter to encapsulate rendering logic
* improve: wrap info section to encapsulate rendering logic
* improve: wrap servers plugin to encapsulate rendering logic
* improve: added tests for schemes-wrapper rendering logic
* improve: added tests for info-wrapper rendering logic, also do not render info if info is undefined
* improve: added tests for filter rendering logic
* improve: added tests for servers-wrapper rendering logic
* `InfoWrapper` -> `InfoContainer`
* add `containers` alias to Babel configuration
* `SchemesWrapper` -> `SchemesContainer`
* drop `container` from container file names
* `ServersWrapper` -> `ServersContainer`
* `Filter` -> `FilterContainer`
* follow `core/containers` pattern in BasePreset
