fix(organize): exclude Civitai meta tags from folder names (#1119)

Follow-up to the keyword-dump guard. The reported model's tag list is
["lora, character, ... face", "base model"], so skipping the dump left the
"base model" label to be picked as the folder name. That label describes
Civitai's listing rather than the model's content, which makes it as
meaningless as a folder as the blob was.

Add CIVITAI_META_TAGS and is_civitai_meta_tag(), and skip those labels in
the automatic fallback. An explicit priority entry still matches them, so a
user who does want a "base model" folder can configure one.

The reported model now resolves to "Krea 2/no tags" instead of
"Krea 2/base model".

Also correct a comment that listed ".civitai.info" among the files sitting
next to a model. LoRA Manager only reads that sidecar -- other tools write
it -- and writes ".metadata.json" itself.
