fix(lora-loader): preserve repeated spaces inside lora names

Whitespace cleanup in cleanupLoraSyntax() and the autocomplete blur
formatter collapsed all whitespace runs, including inside <lora:...>
tags. A file named 'test -  0021.safetensors' was rewritten to
'test - 0021' in the node text, so runtime file resolution failed.

Protect lora tags with placeholders (or segment splitting) so only
whitespace between entries is normalized; names inside tags are kept
byte-for-byte.
