e30: S10F7 broadcast terminal display

Adds the last terminal-services message: a multi-line broadcast push
to all terminals, no reply.  Same TID+lines body as S10F5, W=0.

Generated via the catalog: data/messages.yaml schema entry +
auto-generated s10f7_terminal_display_broadcast / parse_s10f7.

Test round-trips TID and a 3-line broadcast through the builder
and parser, confirms W=0.

COMPLIANCE.md updated: S10F7 row in §5 added; §8 "out of scope"
entry removed.
