Refine HAL, network config, and allocator

Updates across lib-hal and lib-network:

- lib-hal/include/gd32/hal.h: bump copyright to 2025-2026; add IWYU pragma comments for gd32.h, softwaretimers.h and hwclock.h; simplify USB host conditional and always use usbh_core_task(&usb_host) when ENABLE_USB_HOST is defined.

- lib-network/config/net_config.h: bump copyright to 2026; add RFC-1123 hostname validity notes; increase TCP_MAX_TCBS_ALLOWED on desktop builds from 16 to 32; change HOST_NAME_PREFIX values to use hyphens instead of underscores for H3 and other targets.

- lib-network/src/core/network_memory.h: increase network memory blocks from 8 to 12 and improve allocator diagnostics by changing error messages to "Allocate:Full!\n".

These changes adjust build/include handling, improve hostname defaults, expand networking resources, and make allocator failures clearer.
