Function prototypes can be moved out of to_lab_app.c

• I reviewed the Contributing Guide.
• I performed a cursory search to see if the bug report is relevant, not redundant, nor in conflict with other tickets.

Describe the bug
These prototypes can/should be moved out of to_lab_app.c into the header file, along with the global data struct definition.

Code snips

Expected behavior
Consistent content of implementation/header files across cFS.
