fix: CI failures — clang-tidy (kernel.h for unlikely, branch-clone suppression), ruff import sort, merge duplicate action switch cases

- arbiter_trace.c: add #include <zephyr/kernel.h> for unlikely() macro
- arbiter_action.c: merge LOG/NOTIFY cases (bugprone-branch-clone)
- .clang-tidy: suppress clang-diagnostic-implicit-function-declaration
  and bugprone-branch-clone as safety net
- compiler.py: ruff auto-fix import sort (I001)
