docs(wiki): catch concept pages up to the booth-UX/shift/font-scale work

Bring three queryable pages current with the booth-UX commit (cce99aa) whose
breadth hadn't propagated:
- booth-console: Active Sessions as a real table, dropped status column/filter,
  inline live-feed rows, removed TARGE via-badge + redundant Direction filter,
  plate now searchable + backfilled via plate-recognized WS push, per-user font scale.
- shift: Z-report display simplified (shitje dropped, opening cash added) while
  the signed payload is untouched.
- i18n: users.font_scale recorded alongside language/theme as the matching
  per-user server-stored pref (migration 0014).
