[PATCH 4/7] tuna: Remove obsolete apply command functionality

Remove the broken apply command infrastructure that was disabled in
commit 959a16ce. The apply functionality conflicts with the recommended
tuned-based workflow for sysctl profile management.

Removed:
- apply_config() function (only called from commented-out code)
- Commented-out apply command handler
- Unused "profilename" argument definition
- Debug print statement in config.py
- Unreachable comment after raise statement
