feat: Badge EDS 2.0 (#4999)

* feat: Badge EDS 2.0 component

Closes #4791

* docs: improve Badge stories — add descriptions, fix fonts, rework MultipleLabels

* docs: add Density story to Badge

* fix: remove neutral-specific padding override from Badge

* fix: address Badge PR review — density rules, token semantics, test queries, TS typing

* fix: remove explicit comfortable density override — spacing tokens adapt automatically

* fix: address Badge PR review — bolder token, outline var, inline non-overridden vars

- Use --eds-typography-ui-body-sm-font-weight-bolder instead of hardcoded 500
- Introduce --_outline-color pseudo-private var to consolidate duplicated outline declarations
- Inline color, padding-block, padding-inline tokens directly (no variant ever overrides them)
