feat(system): report remote syslog, LuCI state and bridge STP

get_system_config() already parsed the whole system section but returned
only a slice of it, so netOrk had no IST side for three AP-profile fields
and could not compare them at all — the fields were editable, stored and
silently ineffective.

Adds:
  * syslog_remote / syslog_ip / syslog_port / syslog_proto — read from the
    system section that was already being parsed. log_remote gates the
    others: OpenWrt ships nothing without it, so a leftover log_ip must
    not read as an active target.
  * luci_enabled — from the uhttpd init script rather than its listener
    config, so the answer stays "is the web UI served" and re-enabling
    restores whatever was configured before.
  * bridge_stp — None when there is no br-ap at all, which is a different
    statement from "bridge without STP" and has to stay distinguishable.
