View › Hide Template (Cmd+Shift+W): template layers leave the canvas and come back (#2000)

Illustrator's View menu has Hide/Show Template (Shift+Ctrl+W) to leave
template layers off the screen while tracing. VectorCraft drew them (dimmed)
whatever the view, with no way to hide them short of disabling the template
option on each layer and losing the dimming.

- `view.template` toggles `ViewFlags::templates` (default on, kept across
  settings files); the View menu lists Hide Template after Lock Slices, and
  the label flips to Show Template.
- The canvas renders with the new `RenderOptions::hide_templates`, which
  leaves template layers out and nothing else; `skip_templates` (exports and
  thumbnails) also drops guide paths, so it is not reused.
- The fifteen menu catalogs translate both labels; `DYNAMIC_LABELS` lists them.

Tests: render `hide_template_leaves_only_the_template_layers_out` (the
template layer's square and image go, a guide path on another layer stays);
canvas `hide_template_leaves_template_layers_off_the_canvas` (real egui
frames: painted pixels, none after Hide Template, the same after Show
Template, each re-rendering once); the dynamic-label and catalog tests cover
the new pair.
