Jack Ling 75f89f19ba feat(database/gdb): add MaxIdleConnTime configuration for SetConnMaxIdleTime support (#4625) ...

## Summary
- Add `MaxIdleConnTime` configuration field to support Go 1.15+
`sql.DB.SetConnMaxIdleTime()` method
- Add `SetMaxIdleConnTime()` method to DB interface and Core
implementation
- Apply configuration during connection pool initialization
- Add unit tests for the new configuration option

## Related Issue
Closes #4596

## Changes
| File | Change |
|------|--------|
| `database/gdb/gdb_core_config.go` | Add `MaxIdleConnTime` field to
`ConfigNode`, add `SetMaxIdleConnTime()` method |
| `database/gdb/gdb.go` | Add interface method, `dynamicConfig` field,
initialization logic |
| `database/gdb/gdb_z_core_config_test.go` | Add unit test for
`SetMaxIdleConnTime` |
| `database/gdb/gdb_z_core_config_external_test.go` | Add `ConfigNode`
connection pool settings test |

## Usage
**Configuration file:**
```yaml
database:
  default:
    maxIdleTime: "10s"  # Close idle connections after 10 seconds
```

**Code:**
```go
db.SetMaxIdleConnTime(10 * time.Second)
```

## Test Plan
- [x] Unit tests pass (`go test -run
"Test_Core_SetMaxConnections|Test_ConfigNode_ConnectionPoolSettings"`)
- [x] All database drivers compile successfully (mysql, pgsql, sqlite,
clickhouse, dm, mssql, oracle, etc.)
- [x] No breaking changes - follows Go's default behavior (0 = no idle
time limit)
