* Fix investments retrieval
Problem Summary
Stock prices for securities like European stocks become stale because:
1. sync_all_accounts runs at 2:22 UTC (before European markets open)
2. Provider doesn't have today's price yet, so importer gap-fills with LOCF (yesterday's price)
3. Later import_market_data at 22:00 UTC sees all prices exist and skips fetching
4. Real closing price is never retrieved
Solution Overview
Add a provisional boolean column to mark gap-filled prices that should be re-fetched.
* Update schema.rb
