Bundle vconsole.conf in the initramfs so Plymouth uses the right keymap at the LUKS prompt

Plymouth 26 reads the keyboard layout from /etc/vconsole.conf, but the keymap
hook only bakes in the compiled keymap.bin, not the config file, so the LUKS
prompt falls back to US QWERTY. Add FILES+=(/etc/vconsole.conf) to
omarchy_hooks.conf so the initramfs carries it. New installs pick it up via
limine-snapper.sh; existing installs get it through a migration that rebuilds
the UKI. Additive — keymap.bin is unchanged, so no extra lockout risk.

Closes #6183. Related to #6151 and #6072.
