## Summary
Adds custom status messages that are shown under the previews in order
to provide additional progress feedback to the user
Nodes matching the words:
Save, Preview -> Saving
Load, Loader -> Loading
Encode -> Encoding
Decode -> Decoding
Compile, Conditioning, Merge, -> Processing
Upscale, Resize -> Resizing
ToVideo -> Generating video
Specific nodes:
KSampler, KSamplerAdvanced, SamplerCustom, SamplerCustomAdvanced ->
Generating
Video Slice, GetVideoComponents, CreateVideo -> Processing video
TrainLoraNode -> Training
## Changes
- **What**:
- add specific node lookups for non-easily matchable patterns
- add regex based matching for common patterns
- show on both latent preview & skeleton preview
- allow app mode workflow authors to override status with custom
property `Execution Message` (no UI for doing this)
## Review Focus
This is purely pattern/lookup based, in future we could update the
backend node schema to allow nodes to define their own status key.
