Add ES-DE <sortname> import and edit support for ROM ordering

[Copilot]

ES-DE gamelist.xml imports were ignoring <sortname>, so collections with Kanji/Hanzi titles could not preserve the intended library ordering. This change imports that field, uses it for ROM name sorting without changing the displayed title, and exposes it as an editable ROM field.

• Import ES-DE sort metadata

  • Parse <sortname> from gamelist.xml
  • Preserve it in gamelist metadata and on the ROM record as sort_name

• Use sort_name for ordering

  • Prefer Rom.sort_name over Rom.name when ordering by name
  • Keep name as the display title; only sort behavior changes

• Persist the new field

  • Add a migration introducing nullable roms.sort_name

• Expose sort_name for editing

  • Include sort_name in ROM read/update API schemas
  • Add sort_name to the ROM edit dialog so it can be changed manually
  • Clear sort_name when metadata is unmatched

• Cover the new behavior

  • Add parser coverage for <sortname>
  • Add DB-level coverage proving name ordering follows sort_name when present
  • Add endpoint coverage for editing and clearing sort_name

<game>
  <path>./akumajou-dracula.zip</path>
  <name>悪魔城ドラキュラ</name>
  <sortname>Akumajou Dracula</sortname>
</game>

With this imported, the ROM still displays as 悪魔城ドラキュラ, but name sorting uses Akumajou Dracula. The imported sort title can also be reviewed and edited later from the ROM edit form.

Addressed in 3f98aa1: sort_name is now exposed through the ROM update API and edit dialog, and unmatching metadata clears it as well.
