Why do this when setting the APN?

That’s because the PDP context is being configured there.
From my understanding, based on the HL78xx FOTA Guidelines r5 (Document 2174223):
4.1.1 PDP Context
The module uses UDP (CoAP) to communicate with AirVantage to create DM sessions.
A PDP context can be assigned for this connection using AT+WDSS=2,, where is the PDP context
identifier as configured with AT+CGDCONT. The change initiated by AT+WDSS=2, only takes effect while
syncing with the AVMS server. It does not affect the FOTA package download. For HL780x, HL780x always uses
CID1 for FOTA whatever the CID setting in +WDSS command is.
Send AT+WDSS? to check the current APN settings. If an APN has not been specified, CME Error 650 will occur when
trying to initiate a connection.
Here it's also their practice:

| CONFIG_MODEM_HL78XX_RAT_M1=y | ||
| CONFIG_MODEM_HL78XX_DEV_STARTUP_TIME_MS=120 | ||
| CONFIG_MODEM_HL78XX_DEV_SHUTDOWN_TIME_MS=120 |

Add these same options for mg100.conf

This PR enhances the HL78xx modem driver with two key features:
These additions improve both development workflow (through shell access) and device maintainability (through AirVantage-based updates).
