Render modals now remember and restore the user's last setup per image,
surviving close/reopen and restart, via a server-side sidecar keyed by image
content hash.
- New core/modal_setup_api.py sidecar (sibling of edit-docs): POST(merge per
kind)/GET/DELETE, manifest + binary planes, LRU budget, tombstone-aware.
- Re-pose: AUTO-restores recipe/model/prompt/strength and the full 3D pose on
open (seed-before-mount), lineage-aware so a re-posed result/edit resumes its
source's setup. Plus a Re-Apply button.
- Inpaint: restores engine/mode/dials, the PuLID/Style-Reference cluster, the
prompt, and the painted mask (alpha plane).
- Upscale: restores dials + prompt via an opt-in chip, doc-dims keyed.
- Also: before/after Compare wipe on Upscale + Re-pose; Fit/Compare controls
relocated with click-fix + double-click-to-fit.
