Configuring logging at module import time hard-failed in environments
without write access to the user's home directory (sandboxed pytest
runners, restricted CI containers, read-only filesystems). The
unhandled OSError/PermissionError aborted module import and cascaded
into ~100 test failures during collection.
Wrap the FileHandler setup in try/except and fall back to console-only
logging when the log directory cannot be created. Production behavior
is unchanged - file logging in ~/.kicad-mcp/logs is still used
whenever the directory is writable.
Also picks up an isort-driven import reorder applied by the project's
pre-commit hook.
