fix: Fix incompatible function pointer types with g_timeout_add_full on GCC 15

GCC 15 enforces stricter type checking for function pointers, which caused
compilation errors when passing `handle_tap` and `handle_tap_destroy` to
`g_timeout_add_full`. These functions were declared without parameters,
but must match the expected signatures:

- GSourceFunc:      gboolean (*)(gpointer)
- GDestroyNotify:   void (*)(gpointer)

Log: This patch updates the function signatures to ensure compatibility
without changing their runtime behavior, as the `gpointer` parameter
is unused in both functions.
