Localize mega-cap strategy status name

[Pigbibi]

Summary

• rename the zh notification label for mega_cap_leader_rotation_top50_balanced to 美股超大盘50强平衡龙头轮动
• expose display_name_zh in strategy profile status output for settings/switching UIs
• update shared strategy package pins to the localized display-name builds

Tests

• python -m py_compile notifications/telegram.py scripts/print_strategy_profile_status.py
• git diff --check
• i18n scan: only SOXL/SOXX ticker remains in zh text; en locale has no CJK

Note: full platform tests require pandas through strategy runtime imports; not installed on this VPS.
