feat(config-vault): Add device provisioning system
Implement full provisioning workflow for SecuBox device replication:
Auto-Restore:
- import-clone <file> --apply: Auto-restore all modules after import
- restore-all: Restore all modules from vault
Remote Provisioning:
- provision <node|all>: Push clone to remote nodes via RPC proxy
- Transfer clone as base64 to remote node
- Trigger import+apply on remote
First-Boot Pull:
- pull-config <master>: Pull config from master node
- HTTP download or RPC fallback
- Auto-reboot after apply, marks /etc/secubox-provisioned
HTTP Serve:
- serve-clone: Generate clone at /www/config-vault/
- Enables HTTP-based config distribution
RPCD Methods (6 new):
- restore_all, import_apply, provision
- pull_config, export_clone_b64, serve_clone
