feat: mandatory speech bubbles in story panels, v0.26.0v0.26.0

Two-part fix for missing dialogue bubbles:

1. Panel script prompt: each panel description must include quoted Bulgarian
   dialogue for the character to speak/think. At least 3 of 4 panels per page
   must have speech or thought text in the description.

2. Image prompt: added MANDATORY SPEECH BUBBLES block requiring at least 3 of 4
   panels to contain a bubble, describing exact white-background/black-outline
   style for speech and cloud-shape for thought bubbles, all text Bulgarian Cyrillic.
