feat(import): bulk tool import (CSV/JSON/YAML) for admins; NetBox-style help button

- Add POST /admin/tools/import with format auto-detect, CSV delimiters
  (comma/semicolon/tab), per-row validation via CreateToolBody, bulk insert,
  audit log entries per imported tool; gated by new 'tool-import' feature
  flag (premium/enterprise; admins always pass)
- Add tool-import-dialog UI (format tabs, delimiter select, textarea, file
  upload, result/error list) behind hasFeature('tool-import')
- Replace FieldHelp question marks and bare GuideHelp links with a NetBox-style
  'Hilfe/Help' outline button (HelpCircle + text) in form headers only
- Sync locales to 482 keys per language (de/en), update handbook docs
  (administration import section, index/plaene feature tables), regenerate
  API client + zod schemas, add yaml dependency
