fix: MTF bot code review — conditional slicing, caching, tests

- Add _remove_incomplete_candle() for timestamp-based conditional
  slicing on both 15m and 1h data (replaces hardcoded [:-1])
- Add MetaFilter indicator caching to eliminate 3x duplicate calc
- Fix notifier encapsulation (_send → notify_info public API)
- Remove DataFetcher.poll_update() dead code
- Fix evaluate_oos.py symbol typo (xrpusdtusdt → xrpusdt)
- Add 20 pytest unit tests for MetaFilter, TriggerStrategy,
  ExecutionManager, and _remove_incomplete_candle
