QImageReader.text() collapses newlines inside PNG text chunks, so multi-line prompts imported via import_prompt_from_file() were flattened to a single line (issue Acly#2565). Add Image.read_png_text(), which parses tEXt/zTXt/iTXt chunks directly (mirroring the existing manual-write path save_png_w_itxt) and keeps the text byte-for-byte. import_prompt_from_file() now reads PNG metadata through it; non-PNG formats still fall back to Qt.

Problem: QImageReader.text() collapsed newlines inside PNG text chunks then flattened them to a single line.
What this code does now is:
