[codex] Fix combo bot display name

[Pigbibi]

Summary

• fix periodic bot status fallback for crypto_equity_combo
• add English/Chinese display name translations for combo profile
• cover combo heartbeat display name with regression tests

Root cause

main.maybe_send_periodic_btc_status_report() resolved the default status strategy name with a hard-coded Crypto Live Pool Rotation fallback when no display name was passed. The combo profile also lacked legacy i18n keys, so direct heartbeat calls could show the old/default strategy name.
