Subject: [PATCH] refactor: add shared utilities and replace console.log with
 logger

- Add shared action-utils.ts with getCurrentUserId and requireAuth helpers
- Add shared constants for anki defaults (FIELD_SEPARATOR, DEFAULT_NEW_PER_DAY, DEFAULT_REV_PER_DAY)
- Add shared time constants (SECONDS_PER_DAY, MS_PER_DAY, etc.)
- Replace console.error with logger in auth.ts
