Pointer-based per-painter history of the canonical maps with copy-on-write
sharing (only maps touched by a stroke are cloned). A stroke (press..release)
is one step; a Load resets the history to the loaded maps as the sole baseline.
Network sync replicates undo/redo as tiny checkpoint/restore commands instead
of broadcasting full map snapshots: every peer runs the same COW history keyed
by owner-assigned checkpoint ids and reproduces restores locally. A peer that
cannot reproduce a target (undo across its join boundary) requests a targeted
snapshot from the owner as fallback.
Hardening: ordered send FIFO keeps stamps + checkpoints + restores in
production order (a marker never overtakes the stamps it finalizes); stamp
overflow carries over to the next frame instead of being decimated, so remote
content matches the owner; remote always inserts the checkpoint id to stay
1:1 aligned. Owner-authoritative snapshot fallback replaces the silent
host no-op. Adds a logSync toggle (default on) tracing when each
checkpoint/restore/snapshot is sent, applied, or falls back.
Also includes paintings-panel layout tuning in PaintHudPanel.prefab
(inspector edits).

Persistence rework:
- Drop auto-load on setup and auto-save on teardown; the painter now always
seeds fresh from the material.
- Named slots under MeshPaint/Saved/<name>.paint via the existing CHMP
machinery: SavePaintAs / LoadPaintByName / DeletePaint / ListSavedPaintings /
PaintExists. Slot files carry the display name in the header.
- Remove the obsolete persistence partials (PlayerCharacterController,
PlayerPoseController, ThirdPersonOrbitInput) and their references.
Paintings HUD panel:
- Authored Panel_Paintings + Save/Load/Delete dialogs into PaintHudPanel.prefab
(TMP throughout); PaintHud.Library.cs is now a pure binder that clones the
entry template per slot.
- Save dialog blocks empty/existing names; Load and Delete confirm first.
- Fix dialog z-order: open dialogs SetAsLastSibling so a dragged panel can no
longer cover them.
- Lib_ListContent horizontal offsets corrected to 0 (was clipping entry labels
out of the masked viewport).
Multiplayer:
- Loading a painting re-syncs to all peers via the snapshot broadcast path
(BroadcastLoadedPaint), covering later late-joiners for free.

Add MeshPainter.Persistence.cs: auto-save the three canonical paint maps
(albedo, MSO, emission) as PNGs under persistentDataPath on quit/play-stop
and auto-load them as the backend seed on start, so painting survives
sessions. Reuses the existing ReadCanonical/SetupBackend seed round-trip;
no new color-space code.
Add PaintHud.Persistence.cs: auto-save draggable panel positions and the
widget-bound painter values to a small JSON layout file, restored on start
via the painter -> SyncFromPainter -> widgets path. Complete SyncFromPainter
to also cover the spray sliders.
