Store detail page now shows all platform subscriptions instead of always
"No Subscription Found". Subscriptions listing page renamed from Store
to Merchant throughout (template, JS, menu, i18n) with Platform column
added. Tiers API supports platform_id filtering.
Merchant detail page no longer hardcodes 'oms' platform — loads all
platforms, shows subscription cards per platform with labels, and the
Create Subscription modal includes a platform selector with
platform-filtered tiers. Create button always accessible in Quick Actions.
Edit modal on /admin/subscriptions loads tiers from API filtered by
platform instead of hardcoded options, sends tier_code (not tier) to
match PATCH schema, and shows platform context.

Move subscription create/edit from store detail (broken endpoint) to merchant
detail page with proper modal UI. Seed 4 subscription tiers (Essential,
Professional, Business, Enterprise) in init_production.py. Also includes
cross-module dependency declarations, store domain platform_id migration,
platform context middleware, CMS route fixes, and migration backups.
