🐛 Preserve Inkscape labels when pasting SVGs (#9252)
Steps to reproduce: paste an SVG authored in Inkscape (or any editor
that follows the inkscape:label convention) into a penpot file. The
group/element names visible in the source editor are dropped — penpot
shows generic auto-ids like 'g1234' or 'path5678' instead.

Root cause: parse-svg-element in common/src/app/common/files/shapes_
builder.cljc derived the shape name from (or (:id attrs) (tag->name
tag)). Inkscape stores user-given element labels in the inkscape:label
and sodipodi:label namespaced attributes while id holds an auto-
generated technical id, so the operator's chosen name was always
overridden by the technical id when present.

tubax/xml->clj (the SVG parser the import pipeline already uses for
upload, paste, and library import) keeps namespaced attributes as
:prefix:name keywords — the same shape this file already reads
:xlink:href from on line 134, and that app.common.svg uses for the
xlink: namespace at lines 300-307.

Fix: extract the name-resolution logic into a public resolve-element-
name helper that prefers :inkscape:label, then :sodipodi:label, then
:id, then (tag->name tag). Existing SVGs that don't carry either label
namespace fall through the same chain as before, so the behaviour for
non-Inkscape-authored SVGs is unchanged.

This restores the behaviour dfelinto's penpot-icon-generator-plugin
relies on (linked from the issue body) — that plugin reads element
names from the imported SVG to map Blender icons to penpot components.

Tests: 6 deftest blocks in common/test/common_tests/files/shapes_
builder_test.cljc covering the priority order (inkscape > sodipodi >
id > tag), each fallback in isolation, and the empty-attrs case.
Registered in common-tests.runner.

Closes #7869
