refactor: remove Schattenmarkt from all user-visible UI strings

- Pipeline.tsx: FUTURE_AVAILABILITY label → 'Future Availability'
- ReminderTypeBadge: SCHATTENMARKT_RELEASE label → 'Pre-Market'
- ReminderFilterBar: SCHATTENMARKT_RELEASE label → 'Pre-Market'
- ReminderKpiBar: 'Schattenmarkt-Risiko' → 'Pre-Market Risiko'
- ReminderDetailDrawer: section title + switch label → 'Pre-Market'
- mock-data/matches: explainabilitySummary → 'Pre-Market freigegeben'
- mock-data/reminders: notes → 'Pre-Market Freigabe'

Internal identifiers (schattenmarktRelease field, useSchattenmarktSignals hook,
signal ID prefix schattenmarkt-*) are unchanged — renaming them touches too many
call sites for no user-visible gain.
