feat(clone): add hotel field to clone source presets

- CloneSource interface now has a hotel field (maps to habbo_gamedata_hotel)
- DEFAULT_SOURCES presets include their associated hotel (it/com)
- When cloning from a source with a hotel configured, habbo_gamedata_hotel
  is set automatically so official furnidata enrichment uses the correct locale
- Clone source form UI now has a hotel select dropdown
- Source list shows the hotel label when configured
- Clone API route passes hotel through to upsertSource
