Feature Request: Customizable Wi-Fi Retry Behavior for WifiConfig 2

[ChazBurkhart]

My Tasmota devices are configured with WifiConfig 2, which launches Wi-Fi Manager (at 192.168.4.1) for 3 minutes after failing to connect to a Wi-Fi network, then reboots and retries. This is helpful in general, especially when moving devices between networks or houses.

However, I've noticed an issue after power outages:
My router takes longer than 3 minutes to fully reboot and become operational. As a result, many of my devices re-enter Wi-Fi Manager mode before the router is ready, and I have to manually reconfigure them.

Proposed Solutions (any of the following would help):

1. Allow customization of the 3-minute Wi-Fi Manager timeout before rebooting.

2. Enable Wi-Fi Manager to retry connecting to the saved Wi-Fi network periodically (e.g., every 5 minutes), without requiring a manual reboot or intervention.

3. Add an option for the device to stay in Wi-Fi Manager mode longer (e.g., 10 minutes) before rebooting and retrying.

This would preserve the benefits of WifiConfig 2 for mobility and easy reconfiguration, while also making it more resilient in power outage scenarios.

Thank you for considering this enhancement!

Did a small test with WifiConfig 2. Powered off a test AP (to which it was connected), and saw WifiManager become active for the usual 3 minutes. After that, the Tasmota device restarted, and still seeing no AP to connect to, it again switched to WifiManager mode for 3 minutes. Then I powered up the test AP again, allowing Tasmota again to restart after the 2nd 3-minute interval. As the test AP was running again, it connected without problems.

This is basically your second proposal, with automatic connect to the AP without any manual steps on the device.

Beware that having devices running with WifiConfig 2 is pretty bad security.
