Fix chunked TTS failing on newline-delimited text (e.g. German bullet lists)

Browse Source 
splitTextIntoChunks only split on sentence terminators (.!?), so structured
text separated by newlines was never chunked — the full page went as one
request, causing a TCP timeout that the browser reported as "Failed to fetch".

Fix: process each line individually before applying the sentence regex so
newline-separated segments become their own split points. Also move
generation.js from deferred batch E into the main feature batch C so
generateChunkedTts is always defined before the user can click Generate.
