fix(planner): EV session viditelna i bez deadline / nad targetem (BUG2)

Browse Source 
Zivy incident home-01: aktivni plan mel ev_sessions:0, ac session bezela
(target 70 %). Planovac neviděl ~6 kW zatez auta a spatne rozvrhl baterii
(zbytecny vecerni import).

Root cause (dve pasti):
- fn_planning_site_context vracela session jako null, kdyz needed_wh=0
  (auto nad targetem) i kdyz target_deadline is null.
- _ev_session_from_json (Python) zahazovala session bez deadline.

Fix:
- R__038 fn_ev_session_planning_json: session se vyradi (null) JEN bez tvrdych
  dat (kapacita vozidla / soc_at_connect). target_deadline smi byt NULL --
  solver hard deadline constraint aplikuje jen pri needed>0; oportunisticka
  vrstva bezi i bez deadline. Auto nad targetem zustava v planu jako znama
  zatez i s headroomem k levnemu doplneni. R__039 vola helper (deduplikace
  dvou inline poddotazu, SQL-first).
- _ev_session_from_json si NULL deadline ponecha (energy_needed_wh default 0).
- testy test_ev_session_parse.py; docs ev-charging + planning-changelog;
  CLAUDE.md funkce.

Navrh agresivnejsiho oportunistickeho algoritmu (P50 levnych oken z
market_price_stats misto konstanty 1 Kc/kWh) -- NEnasazeno, k rozhodnuti,
sepsano v docs/04-modules/planning.md (EV oportunismus); riziko regrese
golden ekonomiky, nutny EV fixture + eval.

Overeni: pytest -q 362 passed; golden replay gate 7 passed; solver_v2_eval
beze zmeny (fixtures bez EV session).
