This pull request updates the networking configuration and log pattern matching to reflect changes in LTE connection event handling. The main focus is on simplifying and correcting network stack settings and ensuring that all code and tests look for the new log message indicating LTE PDN activation, rather than the previous "Network connectivity established" message.

Key changes include:

Networking configuration and resource adjustments:

  • Refactored network configuration in app/prj.conf to use minimal settings for LTE offloaded sockets, CoAP, and WiFi scan. This includes enabling only IPv4, disabling unnecessary features, increasing network buffer and stack sizes, and adjusting the maximum number of network contexts and connections. [1] [2]
  • Removed WiFi statistics configuration from app/boards/thingy91x_nrf9151_ns.conf to streamline the configuration.

Log pattern updates for LTE connection events:

  • Updated all test scripts and documentation to expect the log message network: lte_lc_evt_handler: PDN connection activated instead of network: l4_event_handler: Network connectivity established for LTE connection events. This affects functional tests for FOTA, MQTT, shell, provisioning, and the getting started documentation. [1] [2] [3] [4] [5] [6]

Remove even more connection manager-specific mentions in tests
and documentation.

Now that connection manager is removed, the RAM requirements
are lower. This patch reduces buffers and stacks to values that
should be sufficient for Wi-Fi and CoAP.
