Add the ideas popup with cached example images; drop the format picker

Ideas popup: 7 themed groups of example prompts in Swedish and English (config/prompt_library.yaml), including a like-real-photos group. Tapping a prompt fills the text box. An unchanged library prompt with no style returns its cached image at once, with no moderation call, provider call or cost, and a note that it is an example. Cached images live in assets/library and are tied to their texts by config/prompt_library.lock.json; a mismatch hides the prompt. scripts/build_library.py makes the images through the normal safety checks (every language of each prompt, and the image) and refreshes the lock.
Create is now always square: the Kvadrat/Liggande/Stående picker and its locale keys are removed (spec 3.3 updated); adapters still accept an aspect.
344 tests pass.
