refactor(nodes): standardize node class names with LM suffix

Rename all node classes to use consistent 'LM' suffix pattern:
- LoraCyclerNode → LoraCyclerLM
- LoraManagerLoader → LoraLoaderLM
- LoraManagerTextLoader → LoraTextLoaderLM
- LoraStacker → LoraStackerLM
- LoraRandomizerNode → LoraRandomizerLM
- LoraPoolNode → LoraPoolLM
- WanVideoLoraSelectFromText → WanVideoLoraTextSelectLM
- DebugMetadata → DebugMetadataLM
- TriggerWordToggle → TriggerWordToggleLM
- PromptLoraManager → PromptLM

Updated:
- Core node class definitions (9 files)
- NODE_CLASS_MAPPINGS in __init__.py
- Node type mappings in node_extractors.py
- All related test imports and references
- Logger prefixes for consistency

Frontend extension names remain unchanged (LoraManager.LoraStacker, etc.)
