Christian Byrne d21ea0f65b fix: loading api-format workflow that contains "parameters" string (#7411)
## Summary

This change extends
https://github.com/Comfy-Org/ComfyUI_frontend/pull/7154 by making sure
the `prompt` metadata tag is parsed before the legacy A1111 fallback
when files are dropped onto the canvas.

ComfyUI embeds two structured payloads into every first-class export
format we support (PNG, WEBP, WEBM, MP4/MOV/M4V, GLB, SVG, MP3,
OGG/FLAC, etc.): `workflow`, which is the full editor JSON with layout
state, and `prompt`, which is the API graph sent to `/prompt`.

During import we try format-specific decoders first and only as a last
resort look for an A1111 file by scanning text chunks for a `parameters`
entry. That compatibility path was always meant to be a best-effort
option, but when we refactored the loader it accidentally enforced the
order `workflow → parameters → prompt`. As soon as a dropped asset
contained a `parameters` chunk—something Image Saver’s “A1111
compatibility” mode always adds—the A1111 converter activated and
blocked the subsequent `prompt` loading logic.

PR #7154 already lifted `workflow` ahead of the fallback, yet any file
lacking the `workflow` chunk but holding both `prompt` and `parameters`
still regressed. Reordering to `workflow → prompt → parameters`
preserves the compatibility shim for genuine A1111 exports while
guaranteeing native Comfy metadata always wins, eliminating the entire
class of failures triggered merely by the presence of the word
`parameters` in an unrelated metadata chunk.
