pomwright-v1-5-bridge-migration

Migrate POMWright v1 BasePage page objects to the v1.5 bridge (BasePageV1toV2) as an intermediate step toward v2 PageObject. Use when asked to migrate, convert, or upgrade POMWright page objects from v1 to the bridge, or when working with BasePageV1toV2. Covers: changing class inheritance, translating addSchema/initLocatorSchemas to defineLocators with v2 DSL, updating call-site syntax (getLocator, getNestedLocator, getLocatorSchema), and updating filter/index/update/mutation patterns.
