- move the shared badge primitive and styling out of the form component module
- keep primary-button badge styling working via a data-slot hook instead of a form-local class
- update the import pages and primitive tests to consume the new home for Badge
- fold Show and Notice into a single primitives module with one shared stylesheet
- keep the primitives barrel export intact while shrinking the folder footprint
- consolidate the primitive tests into one combined suite
- move the conditional rendering helper into components/primitives
- use it in the issues board and issue domain host
- keep the issue page and host easier to scan without repeated null branches
