v0.8.74

More live data streams, and shared streams that serve every reader

Changed

• More pages are fed by a stream instead of repeated reads: ARP, Top Talkers (Kid Control
  devices), BGP sessions, simple queues, WireGuard peers, and the firewall's filter, NAT, mangle and
  raw tables (IPv4 and IPv6, only the tab that is open). On the test routers, commands sent per
  minute fell by up to a third.
• Streamed tables keep the router's order, so firewall rules and queues show in the order they are
  matched.

Fixed

• When two parts of MikroDash read the same streamed table (Wi-Fi clients and CAPsMAN, for example),
  whichever started first decided which fields and interval everyone got. A shared stream now carries
  every field each reader needs, at the fastest interval asked for.
• The bridge host table streamed but could never be used, so it was still read on every interval.
• Interface rates set above 5 seconds fell back to one-off reads, because RouterOS refuses a longer
  interval for that menu. They now stream at 5 seconds.
• A streamed table that was empty from the start (no PPP sessions, no BGP) was still read on every
  interval as well.
• The note on a truncated PDF report no longer uses an em dash.

Internal

• The stream table records which live menus still poll, and why.
• DESIGN.md is tracked in the repository again.
• Branch protection on main: no force pushes or deletion.
