Expose ban-time escalation settings in jail detail and config UI

- Backend: Add BantimeEscalation + BantimeEscalationUpdate Pydantic models
  to app/models/config.py; add bantime_escalation field to Jail in jail.py
- Backend: jail_service.get_jail_detail() fetches 7 bantime.* socket commands
  (increment, factor, formula, multipliers, maxtime, rndtime, overalljails)
  and populates bantime_escalation on the returned Jail object
- Backend: config_service.get_jail_config() fetches same 7 commands;
  update_jail_config() writes escalation fields when provided
- Frontend: Add BantimeEscalation + BantimeEscalationUpdate interfaces to
  types/config.ts; extend JailConfig + JailConfigUpdate; extend Jail in
  types/jail.ts
- Frontend: JailDetailPage.tsx adds BantimeEscalationSection component that
  renders only when increment is enabled (shows factor, formula, multipliers,
  max_time, rnd_time, overall_jails)
- Frontend: ConfigPage.tsx JailAccordionPanel adds full escalation edit form
  (Switch for enable/disable, number inputs for factor/max_time/rnd_time,
  text inputs for formula/multipliers, Switch for overall_jails);
  handleSave includes bantime_escalation in the JailConfigUpdate payload
- Tests: Update ConfigPageLogPath.test.tsx mock to include bantime_escalation:null
- Docs: Mark Task 6 as DONE in Tasks.md
