Subject: fix(sddm): set Backgrounds/default as primary and update fallbacks;
 detect themes dir (incl. NixOS) and skip prompt on read-only paths
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Prefer Backgrounds/default for simple_sddm_2; update default.jpg/png if present
- Detect SDDM themes dir under /usr/share and /run/current-system
- Avoid prompting when theme is missing or Backgrounds is not writable (e.g., NixOS)
- Skip runtime changes on NixOS since SDDM isn’t used in that config
