fix(frontend): normalize script import input and move mode toggle to top

Reorder the add-connection dialog so the script mode switch appears
before basic information to improve entry flow.

Normalize script-mode pasted content by trimming lines, removing empty
lines, and ignoring Markdown code fence markers before parsing. Also
update token splitting to handle any whitespace separator, improving
compatibility with varied pasted formats.
