fix: use STATE_DIR instead of hardcoded ~/.openclaw for identity and canvas (#4824)

* fix: use STATE_DIR instead of hardcoded ~/.openclaw for identity and canvas

device-identity.ts and canvas-host/server.ts used hardcoded
path.join(os.homedir(), '.openclaw', ...) ignoring OPENCLAW_STATE_DIR
env var and the resolveStateDir() logic from config/paths.ts.

This caused ~/.openclaw/identity and ~/.openclaw/canvas directories
to be created even when state dir was overridden or resided elsewhere.

* fix: format and remove duplicate imports

* fix: scope state-dir patch + add regression tests (#4824) (thanks @kossoy)

* fix: align state-dir fallbacks in hooks and agent paths (#4824) (thanks @kossoy)
