fix: 修正CGI并固定数据库配置

 The database table contains one time column, `metric_time DATETIME`, which is the source KPI start time. A same-hour rerun replaces that whole batch. After a successful insert, rows for every other hour are deleted in the same transaction. The script refuses to replace a newer database hour with an older source hour.
 
+CGI is generated with fixed rules:

+- NR (`5G干扰监控`, `700M干扰监控`): `{gNBplmn}-{gNBId}-{cellId}`.
+- 4G (the other five source types): `460-00-{eNodeBID}-{小区ID}`, using each source schema's actual equivalent column names.

+MySQL connection values, database `metrix`, and table `interference_hourly_summary` are constants at the top of `main.py`; they are not project environment variables.
