watchdog: fix limit-probe self-match + scrollback dedupe wedge; plan(lvl5): badge shows level only

Night-watch findings (monthly-spend-limit window, ~01:49-04:45):
- probe text said 'usage limit' which matches LIMIT_RE, so a submitted probe
  kept limited_now true forever -> reworded to 'quota window' with a CAUTION
  note (nudge text must never match LIMIT_RE)
- dedupe scanned all 40 captured lines, so once a probe scrolled into the
  conversation no further probe ever fired (builder/adv frozen at nudges=1,
  orchestrator probes degraded to hourly riding the wake scroll) -> dedupe
  now only checks the bottom 8 lines (input area)
Core invariant HELD: zero kill+reboots during the limit window.

plan(lvl5): operator addition - the top-corner level badge (card, dashboard
pill, badge SVG) shows only the level number+color, zero capping info; the
inline per-rung table keeps intentional-skip/unverified detail.
