* Tests: bad-layer-id checks use an id that can't exist (#3343)
Layer ids come from one process-wide counter (shared with document and
smart-object ids, and bumped by ensure_ids_above on file loads). A full
`cargo test` run passes ids like 9999, so a layer a test just created can
get the "bad" id, the command succeeds and the assertion fails at random
(seen on CI in type_extra_cmds::tests::vertical_orientation_renders_columns_inside_the_canvas).
Use u64::MAX, which the counter never reaches, for every "no such layer"
sentinel in the engine and ui-egui tests. Test-only change.

* Tests: use u64::MAX for bad-layer-id sentinels added on main since (#3343)

The Duplicate Layer dialog gains Photoshop's Document: New destination
with a document-Name field (As stays the copy's name, multi-select keeps
names, single group gets the Duplicate Group title). layer.duplicate
takes document index-or-new plus optional documentName, mirroring
channel.duplicate: the new document matches the source canvas, mode,
depth, resolution and profile, holds just the selected layers at their
positions, and becomes active. Smart-object contents are remapped within
the batch so copies are independent of the source. The dialog is fixed to
its content width so no dead strip remains.
* Drag layers onto another document's tab to copy them there (#589)
New engine command layer.copyToDocument copies layers into another
open document as one history step there, converting them to the
destination's colour profile and bit depth, and places them at the
same canvas position, centred, on a point, or at an offset.
In the UI, dragging layers from the Layers panel or with the Move tool
onto another document's tab shows that document (spring-loaded tabs),
and releasing over its canvas drops the copies under the pointer;
Shift keeps the position for same-size documents and centres them
otherwise, as in Photoshop.

* Tab labels: keep #832's full-title label on Photoshop-style tabs; the layer_transfer tests find a tab by it
