Migrate all init scripts from legacy format to .service TOML units

Convert 14 config files from the legacy init script format (plain-text
commands) to the systemd-style TOML .service format. The init daemon
supports both formats; this eliminates the legacy path entirely so that
all services use the richer, more structured TOML unit format.

Key changes per config:
- base.toml: split 00_base into 00_base.service (tmpdir) + 00_sudo.service
  (sudo daemon); remove redundant 00_drivers and 10_net (handled by
  existing .service files from the base recipe)
- minimal.toml: split 30_console into 29_activate_console.service +
  30_console.service + 31_debug_console.service
- desktop-minimal.toml: convert 20_display and 30_console to .service,
  add 29_activate_console and 31_debug_console overrides
- x11.toml: convert 10_dbus, 10_xenv, 20_orbital, 30_console
- redoxer.toml: split 10_net into 10_smolnetd.service + 10_dhcpd.service,
  convert 30_redoxer
- redbear-legacy-*.toml: update override references to .service paths
- acid.toml, auto-test.toml, os-test.toml, sys-build.toml: direct conversions
