Store N in the right variable.

"mea culpa, mea culpa, mea maxima culpa"

Updates to some incorrectly ended strings in the Spanish translation

Update language_de.h

Small corrections

On last commit, some strings were ended with the incorrect character.
This fixes it.

Updates to Spanish language

Reset watchdog in SD init to prevent reboot

From "microseconds" to "milliseconds"

Add missing Spanish language definitions.

If the watchdog is enabled and bootscreen + SD card checks take too long, Marlin may hang at boot time because of the reset loop. We have this happen all the time with the Anet board if no SD card is inserted.

code_value_float tweak

Disable SD Detect for K8400

Correction to #5629

As a showcase function for how to do waiting in the lcd menu, this function should be preserved.

Fix empty Prepare menu

Use index macro instead of e

delay() is milliseconds

Better sanity check for FILAMENT_CHANGE_FEATURE, FILAMENT_RUNOUT_SCRIPT

Add missing Spanish language definitions.

Drop biv2.5 delta configurations

Define ADV_NEVER, ADV_RATE

Allow M600 when dryrun debugging

LIN_ADVANCE with unified stepper ISR

Add symbol-strings

Update language_de.h

Fix 5194

Suppress warning

Update Japanese translation

Added tarnslation for
```
#define MSG_DEBUG_MENU 
#define MSG_PROGRESS_BAR_TEST
```

Followup to #5550 - spacing before "mm"

I have been a bit too radical in cleaning up this section.

・Add new translation

Allow negative retract values in the LCD

Add description for choice of DEFAULT_DUAL_X_CARRIAGE_MODE

Replace "+mm" with "mm." Allow negative recover-swap length.

- Japanese and Chinese still need update
