- load_price_snapshot picked the last snapshot by filename (lexicographic),
selecting a stale 9-symbol collection over the full 50-symbol universe. Now
picks the snapshot with the latest source.retrieved_at.
- allocate_capital profit buckets now also require momentum > 0 (a falling-price
name is not 'ทำกำไร'), while momentum/theme_signal stay Optional so the PIT
backtest path (which doesn't provide them) still allocates.
- Suggestion now allocates across all 50 SET50 names (B1: BGRIM,TTB; B2: BANPU;
B3: ADVANC,SCB,LH).
- Regression tests for both. Full suite 374 green.
