PFW-1542 Don't allow starting SD print if there is a thermal or fan error

[gudnimg]

Two small fixes:

• Don't allow starting SD print if there is a thermal or fan error. Here I am reusing the exact same conditions which are applied to "Resume print" feature.
• Reset the status line message when the fan error is resolved automatically to show "Prusa i3 MK3S OK" instead of "Err:HOTEND FAN ERROR"

Steps to reproduce issue:

1. Start a print
2. Once the purge line is started to extrude => block the hotend fan until error appears
3. Print is paused due to fan error (note that the print can’t be resumed)
4. Keep blocking the fan and stop the print
5. Observe issue: A new print can be started even if the fan error is still active/unresolved.

Test results from #4450
Tested on MK404

1. Stall fan
2. Start SD print
3. 65~ish Err:HOTEND FAN ERROR detected ✔️
4. Resume fan --> Resume menu ✔️
5. Stall fan --> Err:HOTEND FAN ERROR ✔️
6. Again and again these steps ✔️

2nd test

1. Stall fan
2. Start SD print
3. 65~ish Err:HOTEND FAN ERROR detected ✔️
4. Stop print
5. Err:HOTEND FAN ERROR
6. Limited menu without Print SD ✔️
   1. But it times out and is shown even
      1. Fan is still stalled
      2. Fan check isn't disabled
      3. Good is that the next Print from SD errors out correctly with stalled fan ✔️
   2. Settings -> Fancheck [Off] works well
7. With Fan check [Off] and stalled fan the print starts ✔️
   1. As soon I turn on in Tune -> Fan check [On] it errors out correctly ✔️
