db-console: statement details component extraction

This change extracts Statements details page and its dependent
components and styles.
- most of the components moved without any changes, only import
paths were adjusted
- styles converted from Styl to SCSS
- modified route paths to ensure they start with "/" root path
(it ensures that routes behave the same way regardless to current
path).
- `util` directory now contain `network` and `nodes` subdirectories
with logic specific to particular entities. It allows avoid extra logic
in redux layer and keep it independently.
