feat(web): rules page with layer cards, rule-string sync, preview and preferences as tags (FE-3)

- /console/rules tabs: rule groups, custom conditions, defaults, acquisition policies, suppressions
- editor: rule string parsed live via /rules/parse (position + suggestions) and synced both ways with layer cards; hard excludes; expectedRevision conflicts keep local edits
- preview against recent releases or pasted titles with pri / level / reasons / trace
- single-rule groups shown as preference tags; disable/delete writes suppression records
- /console/preferences redirects to /console/rules (origin passed through)
