fix: use mjai_to_tid instead of parse_tile_136 for mjai tile parsing

[smly]

Summary

• Fix apply_mjai_event and MjaiReplay::from_jsonl to use mjai_to_tid instead of parse_tile_136 for parsing mjai-format tile strings
• parse_tile_136 only handles mpsz format (1z, 0m, etc.), so mjai-specific tiles (E, S, W, N, P, F, C, 5mr, 5pr, 5sr) were silently mapped to tile ID 0 (1m)
• The existing mjai_to_tid function in parser.rs (previously #[allow(dead_code)]) correctly handles both formats
• Add test_apply_mjai_event_honor_and_red_tiles covering:
  • All 7 honor tiles (E/S/W/N/P/F/C)
  • Red fives (5pr, 5sr)
  • Dora marker with mjai honor string
  • Tsumo/Dahai/Dora events with mjai-format tiles
