feat(G-08): chapter field uses live datalist from resource.chapters

All chapter text inputs now show autocomplete suggestions from the
database (distinct chapter values from active resources) via HTML
<datalist> wired to trpc.resource.chapters:

- ResourceModal: chapter input
- RateCardsClient: rate card line chapter input
- EffortRulesClient: effort rule chapter input
- ExperienceMultipliersClient: replaces hardcoded CHAPTER_PRESETS
  with live data, falls back to presets when no data available

Also revert blueprintRolePresetsInputSchema to z.array(z.unknown())
to restore compatibility with StaffingRequirement[] call sites.
