Root cause: holding_strategies.shares field got set to literal string
'write_holding_strategy' for 6 records, causing TypeError at
price_monitor.py line 611 ('>' not supported between str and int).
Fixes:
1. price_monitor.py: Replace set comprehension with safe loop that
checks isinstance before comparison. Non-numeric shares treated
as holdings for safety.
2. mofin_db.py write_holding_strategy: Add type guard that resets
non-numeric shares to 0 with warning.
3. Data fix: Updated 5 corrupted holding_strategies records from
holdings table (300035/300308/300750/518880/00700).
Set 002594 (watchlist) shares=0.
