svg_candles: cautarea nivelurilor, scoasa in functie comuna; 11 generatoare reparate

Unsprezece generatoare nu mai rulau deloc la HEAD: cautau <line x1="24", iar
svg_candles scrie x1="24.0" de cand are Level.i0. Un generator mort inseamna
ca diagrama nu mai poate fi regenerata, si nimeni n-ar fi aflat pana cand ar
fi incercat cineva, peste luni.

Cele 11 copii ale aceluiasi regex au disparut: y_niveluri() si offset_render()
se agata acum de semnatura liniei de Level (stroke-width + dasharray), nu de
x-ul ei. Caz nou in selftest, cu Level(i0=) si panou de volum - combinatia la
care varianta veche fie crapa, fie prindea tacut linia de zero a volumului.

41 de SVG-uri regenerate, toate identice cu cele comise dupa normalizarea
x1=24 -> x1=24.0, deci niciun desen n-a sarit. Verificarea asta a prins o
regresie reala: la buy_doji_transe substitutia lasase scaderea veche pe randul
urmator, offsetul se scadea de doua ori si desenul urca 92 px.

Inca doua generatoare moarte din aceeasi familie, gasite pe drum
(intrarea_cazul_lui, intrarea_doua_variante): desenau peste grafic citind
ch._y() fara offset. Nu crapau zgomotos - produceau suprapuneri la 22 px.
