docs: standardize man page trailers with AUTHORS, COPYRIGHT, and SEE ALSO

Reorganize the trailing sections of all three man pages (bssh.1,
bssh-keygen.1, bssh-server.8) into a consistent BUGS / AUTHORS /
COPYRIGHT / SEE ALSO order matching common Unix manual conventions.
Author attribution, contact email, Apache-2.0 license notice with the
standard "no warranty" disclaimer, and the project homepage link are
now uniform across all three pages.
