fix(planner): EV tolerance 'dost dobré' — konec honění posledních % do 100 %

Browse Source 
needed_wh=0 když live_soc >= least(target,99) - charge_done_tolerance_pct (V107,
default 3 p.b.). Effective target zastropovaný na 99 (clamp) → bez věčného
mini-dobíjení a cyklování nabíječky. Ověřeno živě: session #6 needed_wh 1329→0.
