Fixed some typos causing compilation failure in some configurations.

No longer copies spindle on delay from door setting ($392) to the new general setting ($340) on update from pre 20250103 builds.
Fixed missed code change when general spindle on delay was implemented causing the delay to be inserted on a simple RPM change with the S word.

+Core:
+
+* Fixed some typos causing compilation failure in some configurations.
+
+* No longer copies spindle on delay from door setting (`$392`) to the new general setting (`$340`) on update from pre 20250103 builds..
+
+* Fixed missed code change when general spindle on delay was implemented causing the delay to be inserted on a simple RPM change with the `S` word.
+
+Drivers:
+
+* STM32F4xx: Allow `$DFU` command if critical alarm is active. Fixed LongBoard32 map for incorrect motor -> axis mapping when four axes where configured.
