feat(multi-chart): refactor _run_multi_tick + fix alert spam pe oscilație strip

Bug critic: _strips_match(tol=10) trip pe pulsații naturale de lățime ~18px între
ticks (ex. 792↔810px). Fiecare trip → _commit_layout_change → reset FSM + alert
Telegram + scheduler stop. Logul 2026-05-04.jsonl arăta 576 evenimente
layout_change/zi, plus prime alerts repetate la dark_red/dark_green (FSM resetat
înghite lockout-ul) și sincronizare cross-chart pe ambele FSM-uri simultan.

Fix:
- main.py:1511 — gate doar pe count change (len(new) != len(current));
  count stabil → silent update sub_roi indiferent de jitter
- main.py:1438 — silent=True pe alert layout_change (Telegram fără sunet)
- 2 teste regresie noi: width oscillation 792↔810 + silent assertion
- 2 teste async reparate: bootstrap _detect_strips_for_ctx pentru ScriptedDetector
  (regresie după ce _run_multi_tick a devenit unica cale de detecție)

Plus refactor multi-chart pre-existent: layout.py modul nou, _detect_strips_for_ctx,
ChartState per-chart FSM/Detector, ROI per-strip pe screenshots, scripts/diag_*.

Verificat: 292 passed, 2 skipped în 10s.
