Support both numeric and string author ID schemas

- Handle numeric author_ids normally (existing schema)
- For string author_ids (alternative schema):
  * Treat the string as the author name
  * Generate deterministic integer ID using MD5 hash
  * Maintain integer author_id constraint in database
- Add comprehensive test coverage for:
  * String author IDs become names with generated IDs
  * Mixed numeric/string author IDs in same item
  * Consistent ID generation for same string values

Supports ~5-10% of Pocket items that use alternative author schema
without breaking existing database structure or functionality.
