v1.1.0: Complete kernel modules, fix WebUI bugs

Kernel modules fully implemented for kernel 6.6/Tensor G5:
- rc_wifi_mon: kprobes kallsyms, bcmdhd iovar monitor/promisc/allmulti,
  sysfs status at /sys/kernel/rc_wifi_mon/, clean unpatch on unload
- rc_shannon_cmd: ioctl interface (AT_CMD, GET_URC, SET_TIMEOUT,
  GET_STATUS, FLUSH), URC ring buffer (64 entries), modem probe on init
- rc_diag_bridge: HDLC decode with CRC-16 validation, FTM ioctl,
  EFS read/write/stat/unlink, version query, subsystem dispatch
- rc_ioctl.h: shared userspace header for all ioctl definitions
- All modules handle class_create() API change in kernel 6.4+

WebUI fixes:
- Fix malformed WiFi firmware JSON output
- Add vonr/vt/apn/nradv to carrier config read endpoint
- Fix carrier toggle state loading in frontend
- Fix redundant replace in kmod toggle logic

Makefile: single-module build (MOD=), make package target
