Move store theme admin pages, templates, and JS from tenancy module
to CMS module where the data layer (model, service, API, schemas)
already lives. Eliminates split ownership.
Moved:
- Route handlers: GET /store-themes, GET /stores/{code}/theme
- Templates: store-theme.html, store-themes.html
- JS: store-theme.js, store-themes.js
- Updated static references: tenancy_static → cms_static
Deleted old tenancy files (no remaining references).
Menu item in CMS definition already pointed to correct route.
