Harvest DragonX packaging + legal artifacts from compliant-rebrand

Legal: correct GPLv3 LICENSE (fixes garbled 'GENERAL GENERAL'), AUTHORS DragonX attribution, COPYING. Packaging: man pages REGENERATED from the 1.0.3 binaries via help2man (dragonxd/dragonx-cli/dragonx-tx.1 -> v1.0.3, correct dates), wired into doc/man/Makefile.am (dist_man1_MANS), orphaned hush*.1 removed. Init/openrc/systemd scripts, Debian packaging (control/changelog/copyright rebranded hush->dragonx + install stubs), example confs taken from origin/compliant-rebrand (c05134e77). REMAINING follow-ups: (1) debian/changelog still tops at 1.0.0 - add a 1.0.3 entry; (2) dragonx-cli --help hardcodes rpcport default 18030 (hush) - fix the HelpMessage string in source then regen. Staged on 176 for review; not pushed.
