chore: improve Supabase migrations via CLI after login and fix compatibility issues

- Update supabase/push-migrations.js:
  - Detect modern Supabase CLI link state (supabase/.temp/project-ref)
  - Prefer `supabase db query --linked --file` (works in this env where direct postgres connections fail with ENOTFOUND/network unreachable)
  - Updated docs/comments for `supabase login` + `supabase link --project-ref wnzkhezyhnfzhkhiflrp` workflow

- Add MEMORY.md capturing the Supabase login/link session, tooling changes, migration patches applied, and gotchas

- Patch migrations for current remote schema (column drift, syntax, idempotency, pre-existing tables):
  - 091_brand_plan_tier.sql: fix extra paren in get_brand_plan_info
  - 145_create_product_images_bucket.sql: allowed_mime_types + DROP POLICY IF EXISTS + safer bucket insert
  - 148_public_stops_rpc.sql: quote reserved "time" column in RETURNS TABLE + SELECT
  - 200_production_features.sql: add ALTER TABLE for user_activity_logs (originated in 036) so policies/indexes validate
  - 201_seed_data.sql: trim demo seeds with outdated column lists (products/stops/etc.); keep only compatible brands insert

- Include 202_fix_admin_create_stop.sql and related stop creation updates (src/actions/stops/create-stop.ts, 147_admin_create_stop_rpcs.sql, ADMIN_CREATE_STOP_FIX.sql)

- Update CLAUDE.md with pointer to MEMORY.md for recent migration work

Applied via the new flow (after supabase login + link): 084, 091, 142–148, 200–202 etc.

Refs: Supabase CLI now linked; use `node supabase/push-migrations.js <prefix>` or `npm run migrate:one NNN`
