feat: add host-local custom project icons (#2335)

* feat(projects): add local icons and colors

* refactor(projects): simplify appearance handling

* fix(projects): serialize appearance saves

* test(app): update project appearance expectations

* test: fix project appearance CI expectations

* refactor(projects): organize appearance code

* fix(server): adopt main's reconcile model in project appearance updates

* fix(projects): preserve host-local appearance targets

* fix(desktop): restore Linux development startup

Ubuntu can block Electron's unprivileged user-namespace fallback while the npm-installed sandbox helper is not SUID. Disable the Chromium process sandbox only in the Linux development runner so packaged desktop policy remains unchanged.

* feat(projects): add custom project icons

Keep URL acquisition in the client so the host daemon only validates uploaded bytes. Project name and icon changes share one adaptive edit sheet.

* refactor(settings): scope projects by host
