fix(review): resolve all review blockers and concerns

- Delete frontend/e2e/nl-search.spec.ts (was left alive; would have
  crashed CI when Playwright couldn't find the deleted SmartModeToggle)
- Fix docs/DEPLOYMENT.md: remove NLP service arrow + key-facts bullet
  that were accidentally added instead of removed in the prior commit
- Clean docs/GLOSSARY.md: remove keyword→tag resolution, PersonHint,
  TagHint, theme chip entries; trim NameMatches to drop the
  NlQueryParserService reference
- Remove @ConfigurationPropertiesScan from FamilienarchivApplication
  (all remaining @ConfigurationProperties beans carry @Component)
- Remove 12 orphaned i18n keys from de/en/es message files
  (search_loading_nl, search_chip_*, search_disambiguation_*, etc.)
- Fix SearchFilterBar.svelte input padding: pr-20 → pr-4 (SmartModeToggle
  that justified the right padding is gone)
- Delete docs/superpowers/plans/2026-06-07-remove-nlp-search.md
  (scaffolding artefact; plan files belong in Gitea issues, not the repo)
- Add docs/adr/034-remove-nl-search.md documenting the removal decision
  (supersedes deleted ADR-028 ×2, ADR-034-ollama, ADR-035)
