Victor Julien bf167418bf detect: reject the '<' hook form for non-firewall rules
The '<' lower bound hook form is a firewall policy construct: the rule
covers its own hook and every prior one. For a threat detection rule the
form has no such meaning, and the flag it sets leaked into the firewall
policy walk, where the rule could influence the per-state decisions.

Reject the form at load for rules without SIG_FLAG_FIREWALL.

Ticket: #8944.

Victor Julien fa695d3563 doc/userguide: TLS firewall state phase rename
The firewall userguide pages still described the old TLS completion
milestones, and an upgrade from the old state names had no guidance.

Update the firewall design and example pages to the phase names,
list the migration page in the firewall index, and add the migration
page itself: the old/new state name mapping, the load-time
validation of rules and config keys, monitoring of ts_progress, and
the semantic changes - the fragmented hello decision, the removed
flight-completion state, one decision per state, the new ja3/ja3s
event timing, and the SSLv2 track behaviour. The 9.0.0 upgrade
guide gains Major Changes (a rule with an old state name fails to
load and is not enforced; config keys renamed) and Logging Changes
(ts_progress/tc_progress values) entries, both linking the
migration page.

Ticket: #9047.

Lukas Sismis b82b4496af detect/firewall: group policies under packet and app nodes
The policy config was a flat map mixing packet hooks and app-layer
protocols: `packet-filter` next to `dns`. There was no node that meant
"the packet hooks" or "the app-layer hooks", so a setting could not be
scoped to one group.

Move each group under its own node:

    packet-filter     -> packet.filter
    packet-pre-flow   -> packet.pre-flow
    packet-pre-stream -> packet.pre-stream
    <proto>.<hook>    -> app.<proto>.<hook>

Lukas Sismis 04c9fd9e22 detect/firewall: address HTTP/1 policies as http1
AppProtoToString(ALPROTO_HTTP1) returns "http", so an HTTP/1 policy had to
be written as `http:` while its rule hooks were already spelled `http1:`.
Use the same name in both places.
