refactor(shared/ui): stop deep-importing sibling config/types (C-3)

Badge and TechText reached into $shared/ui/Label/config, and SearchBar into
$shared/ui/Input/types — bypassing the siblings public surface.

- Label/config.ts was explicitly shared text-styling config, not Labels
  internals; relocate it to shared/ui/labelConfig.ts (a neutral peer module)
  and point Label/Badge/TechText at it relatively.
- inputIconSize is a consumer-facing map; export it from Input/index.ts so
  SearchBar imports it through the barrel alongside Input.
