jpmschweitzerandClaude Sonnet 4.6 add2507eac fix(content): add price_tier to brand layer schema, import, and V-B06 (#828 blocker) ...

price_tier was documented in D-189 §5 and present in brands.toml but
silently discarded on import — absent from schema, INSERT, and V-B06.

- Add price_tier TEXT column to brand_products CREATE TABLE
- Add COLUMN_MIGRATIONS entry for ALTER TABLE on existing DBs
- Add VALID_PRICE_TIERS constant (mass/premium/luxury/flagship/institutional)
- Include price_tier in product_rows tuple and INSERT OR REPLACE
- Add price_tier to V-B06 enum checks; skip NULL (nullable column)
- Backfill 4 pre-amendment anchor brands (8 entries): Calloway flagship/premium,
  VGV luxury/premium, thrds luxury/premium, Bífröst flagship/luxury

V-B01..V-B06 all pass.
