Peekaping is stuck once a monitor goes down (for whatever Reason)

**Describe the bug**
Peekaping is stuck once a monitor goes down (for whatever Reason). I'm not entirely sure why, but once a monitor (Ping or HTTP) goes down, it doesn't come back up (almost ever).

I have also `gatus` and `uptime-kuma` monitoring those Hosts so I know for a Fact that most of them are 100% up.

Regardless of why the monitor came down, it should continuously be pinged (ICMP Ping) / queried (HTTP). Instead, after a while, **Peekaping just gives up even trying anymore**, thus the Monitor is and stays down forever.

**Database**
- postgresql

**Version**
- Peekaping: 0.0.45

**To Reproduce**
Steps to reproduce the behavior:
1. Go to '...'
2. Click on '....'
3. Scroll down to '....'
4. See error

**Expected behavior**
Monitor should continuously be pinged (ICMP Ping) / queried (HTTP) even after it goes down.

This is what `gatus` and `uptime-kuma` do out of the Box.

Peekaping instead seems to get stuck and/or give up after a while 😕.

**Screenshots**
Time is currently between 08h06 (when I started writing this Issue) and 08h22 (when I finished writing this Issue).

EDIT 1: from inside the Containers / Pod, after installing `curl`, I can `curl` the HTTP Endpoints without Issue. `ping` works fine. DNS Resolution works without Issues.

So ... it's something wrong with Peekaping's Binary 😕.

The issue points to the ingester component (ingester/handler.go) and producer (producer/processor.go). Start by examining the task scheduling logic in the ingester to see why it stops processing after a monitor goes down. Look for any state that might cause tasks to be dropped or paused. Check the database for monitor status flags. Reproduce by setting up a test monitor and simulating a failure.
