Update install/update instructions

Add steps to enable the startup service. Add new update instructions based on the update script. Remove instructions for cron job scheduling (startup service + config settings are now used) and adding Wi-Fi connections via nmtui (can now be added in the web app + config file).

-## Schedule Cron Job
-
-To automatically run the recording script after each boot (triggered by the power management
-board), you will have to set up a [cron job](https://en.wikipedia.org/wiki/Cron){target=_blank}.
-
-Open the crontab file for editing by running:
-
-``` bash
-crontab -e
-```
-
-When you are asked to choose an editor, type in `1` and confirm with ++enter++.
-
-Paste the following lines at the end of the crontab file:
-
-``` text
-# Wait 30 seconds after boot to ensure all system services are fully initialized
-# Run Python script with timestamped logging, including potential error messages
-@reboot sleep 30 && { printf "\%s - Running yolo_tracker_save_hqsync.py\n" "$(date +"\%F \%T,\%3N")"; env_insdet/bin/python3 insect-detect/yolo_tracker_save_hqsync.py; } >> insect-detect/cronjob_log.log 2>&1
-```
-
-Exit the editor with ++ctrl+x++ and save the changes with ++y+enter++.
-
-This cron job will wait for 30 seconds after boot (`sleep 30`) to make sure that
-all important services are ready. It will then run the Python script and log its
-execution, including potential error messages, to `insect-detect/cronjob_log.log`.
-
-!!! tip ""
-
-    If you are still in the testing phase, it is highly recommended to deactivate
-    your cronjob by adding `#` in front of `@reboot`. Otherwise each time you are
-    booting up your Raspberry Pi, it will run the Python script.
