HOTFIX: planovac oslepl k autu po prejmenovani wallboxu (hardcoded kody)

fn_planning_site_context (R__039) a fn_load_planning_slots_full (R__063) mely
natvrdo 'ev-charger-1/2' a 'deye-main'. Uzivatel prejmenoval wallboxy na
'vt-ev-charger-1/2' -> ctx.vehicles=[], ev_sessions=[null,null], ev1/ev2_connected
vzdy false -> planovac nevidel auto -> ZADNE nabijeni ani v zapornych cenach
(Tesla 70%, potrebuje 90% do Po 7:00, okno -0.32 Kc ve 13:45 nevyuzite).

Fix: vyber wallboxu DYNAMICKY podle site_id, ev1=nejnizsi ch.id, ev2=druhy
(stabilni, odolne prejmenovani). Inverter pro gen_cutoff pres controllable=true
misto code='deye-main'. Konzistentni R__039 (vehicles order by id, sessions
dynamicke kody) + R__063 (ev1/ev2 connected). Pure SQL, 363 testu zelenych.
