rootiest 1b0e83b1d6 feat(k17_max): enable Keychron RGB and fix EEPROM persistence
Port the Keychron RGB EEPROM persistence work from the Q5 Max (PR #18)
to the K17 Max ANSI Encoder RGB variant.

- Add KEYCHRON_RGB_ENABLE = yes to rules.mk
- Define default_per_key_led[] (red Esc/CapsLock, yellow modifiers and
  numpad, blue alpha keys) and default_region[] for the 103-LED layout
  in ansi_encoder/rgb/rgb.c; both are extern'd by keychron_rgb.c
- Add wireless_enter_connected_kb() hook and eeconfig_init_custom_rgb()
  call in keyboard_post_init_kb() in k17_max.c, matching the Q5 Max
  pattern for boot-time and transport-change RGB persistence
- Define VIA_EEPROM_MAGIC_ADDR 552 in ansi_encoder/rgb/config.h to pin
  VIA keymap storage past the Keychron EEPROM data region end (540 for
  K17 with 103 LEDs); prevents keymap corruption if the KB data block
  grows in future
