chore(cogs): publish cog-ha-matter 0.3.0 + bump signal/sensing-server to 0.3.1

cog-ha-matter required wifi-densepose-sensing-server with the `mqtt`
feature exposed, which crates.io 0.3.0 did not expose. Chain:

  1. wifi-densepose-signal 0.3.0 -> 0.3.1 (already includes
     EmbeddingHistory::{with_sketch,novelty} locally; needed
     republish so sensing-server-0.3.1 can compile against it).
  2. wifi-densepose-sensing-server 0.3.0 -> 0.3.1 (now exposes
     the `mqtt` feature, sensing-server bin links against
     signal-0.3.1 cleanly).
  3. cog-ha-matter sensing-server dep bumped to ^0.3.1; publish=false
     dropped. cog-ha-matter@0.3.0 published.

Both signal and sensing-server published with --no-verify; cargo's
verification step fails on Windows because openblas-src requires
vcpkg (the source itself builds fine in the workspace and on Linux).
