ui: log page tone badge follows the toggle (novice / pro)

The Strategic Log Archive panel header used to show two engineery
badges sourced from server config:
  new logs use: tone intermediate analysis speculative

Both were misleading:
- The tone badge described the SERVER's generator setting, not the
  user's reading preference — confusingly disconnected from the
  Novice | Pro toggle in the topbar that actually controls what AI
  panels render.
- The analysis flag is always SPECULATIVE in production, so the badge
  carried no information.

Drop the "new logs use:" prefix and the analysis badge. The tone badge
now mirrors the user's toggle: NOVICE → "novice", INTERMEDIATE → "pro"
(same data values; just the display label flips, matching the header
relabel from 3e1a14f).

Wiring lives in base.html: a new cassandraSyncToneBadge(tone) helper
updates the #tone-badge element when present. Called from
DOMContentLoaded (so the initial badge picks up the localStorage tone)
and from cassandraSetTone (so toggling the header updates the badge
live, without a page refresh).

current_tone / current_analysis are removed from _log_page_context —
log.html was the only consumer and neither key is referenced now.
