test(ui): add iced interaction harness (#219)

* test(ui): add iced interaction harness

Exercise the real HonkHonk view/update loop headlessly for sort persistence and staged settings search behavior.

Co-Authored-By: Codex <noreply@openai.com>

* ci(test): provide fonts for GUI harness

Install DejaVu fonts in the unit-test job and declare the Arch package as a source-package check dependency so iced_test can shape styled and monospace settings text in minimal environments.
